I've been arrested, held up at gun point, and spent a few weeks in a Texas jail in the 90s because I like smoking weed. Now I have 3 weed stores within 2 miles of me, and it's as mundane as buying a loaf of bread. So that's a positive in my book.

Outside of formal settings, I'd say that it's uncommon for women to wear skirts or dresses in day-to-day life now.

Menswear is considerably more casual. This is a trend that's been going for over a century or so, so it certainly didn't just happen during my life, but it did significantly change in that time.

No smoking indoors anymore. I remember when you could still smoke in a hospital. Then they limited it to just a "smoking lounge" on each floor. Followed eventually by a ban inside...to finally no smoking anywhere on hospital property.

Not to mention airplanes, restaurants and movie theaters.

The mall was full of stores with good quality products that you would value for a non insignificant amount of time if purchased.

I swear that before 9/11, middle eastern people in the US counted as "white", or at least white-but-you-can-make-fun-of-their-accents-and-names like Italians or Polish people did

I got started on the Internet in 1988. You had to learn Unix (Linux didn't exist yet) and the command line (GUI Internet didn't exist yet), and had to manually piece together files to download them (www didn't exist yet).

It still feels a little odd to me that restaurants don't ask "smoking or non?". Don't get me wrong, I'm delighted everything stopped smelling like ash. But it's surreal to remember my grand parents chain smoking over pancakes at Dennys.

Everyone has reduced their perception of the world to a Bad Apple-esque black and white extreme of good or bad. All In Support or Nuclear Strike Disapproval. No inbetweens allowed.

More aggressive driving. Statistics even support it so it's not just an anecdotal thing.

When I was still a kid, we went from bring a plate of cookies to your neighbor and introduce yourself to DON'T TALK TO STRANGERS!!

Extreme drive for individualism leads to the society where nobody cares about others and the strongest wins. I wonder for how long the community can survive in these conditions.

When I was a kid, it was assumed that boys asked girls to dances and not the other way around. In the recent Pixar series Dream Productions, a tween girl is asked who she's going to ask to the school dance. It's now treated as normal for girls to ask boys. She also ends up not going with a date and just going with her friends.

Cable TV use to be something that teathered us all together in a way. We were all stuck on the same schedule for premiers of new episodes of different shows so we all had a common thing to talk about come the next day. Now I have no idea what’s playing on what service and have just given up on staying up to date on the new shows. I could have access to $TVShow but probably won’t watch it because I don’t like to binge watch so it takes me longer to catch up and by the time I do it has already left the minds of my peers so why bother.

Smoking cigarettes isn’t just not cool anymore, You’re actually likely to be socially ostracized in a lot of countries where it used to be popular. My perspective is the US, which is a very clear example of this.

Weed, however, is way more accepted. To the point where if I’m using a vape I almost feel a social pressure to clarify to people I’m getting high and not smoking nicotine.

It’s rather funny when you think about it

The most noticeable change I see is how everyone buys stuff they can't effort all because of how easy it is to get a loan. With interests of course. Now everyone has a house, a car, an expensive smartphone, nice vacations, eats at fancy restaurants and nice café. Compared to previous generation this was mostly impossible for the vast majority of the population.

So life go easy in the facade because everyone just gets a loan.

Cartoons went from the majority of them having a unique enough art style to distinguish them from one another. If you take a silhouette of heads/faces from cartoon characters in the 90s and 2000s ( don't have experience with prior decades besides the standard MGM cartoons, Jetsons/Flintstones, or things like Looney Tunes or Tom and Jerry ) you'd be able to tell the characters apart, even if you don't even know who they are. Try doing that with most all 2010s and upwards new cartoon characters and you'll get the exact same ugly, generic, and sanitized bean shaped head/face/smile imaginable.

There have definitely been some examples that might deviate a little from that mold, like Summer Camp Island, but those are far and few between anymore.

Also, for the most part, I would consider the overall quality as having been declining as well. I haven't seen a lot of shows, so my experience should be taken with a huge lump of salt, but besides shows like Steven Universe, Summer Camp Island, etcetera, the storytelling hasn't been as tight ( all of this in my opinion ), they're banking on you not actually paying attention to the show itself so they can cheap out on every single step, art style is being sanitized and overly simplified to cut costs, and jokes are all devolving into "LOL RANDOM", but that might have been a 2010s thing and I hope it's dead.

It also doesn't help that fans and fandom culture over time have become worse as well as you'll usually find a vocal minority who will kick and scream while doxxing you because you ship the wrong 2 fictional characters together or don't believe their exact highly specific headcannon, regardless of whether you are the creator or nor. Though, I'm debating of getting rid of this section because it might bleed too much into social media.

“no one talks to each other in person, they’re on their phones always”

No one talks to each other on their phones either. They send texts.

Watching UK 70s TV now is wild. Prime time sitcoms using camp gay sterotypes as a punchline in themselves, black characters being called Chalkie or similar. These had regular repeats throughout the 80s on the main TV channels. Hell, known ephebophilie and bigot, Jim Davidson, had a prime time game show till 2002 and would regularly do his Chalkie character on it.

Late 90s/early 2000s UK TV was still pretty homophobic and racist, see Little Britain for yellow and brown face combined with racial stereotypes, big name comedians of the time like Frank Skinner making homophobic jokes.

Early 2000s in the UK was aggressively misogynistic, mostly in the printed press, absolutely rabid.

Obviously these issues haven't been solved, but at least its unacceptable for mainstream TV in the UK to pedal this shit.

I was trying to think of specifics, but they're already getting mentioned. I'd just say a lot of these things stem from there being literally double the amount of humans alive right now than when my dad was born. An individual is devalued immensely and cultural cohesion is completely shot.
