I disagree even with this, though I know it's a common sentiment/expression.

For the first couple of decades of my life, I had little to no to negative money, depending on when we're talking about. Not having money sure was everything.

Since then, I have slowly but steadily improved my financial status. I guess I might be middle class now, but what that means is different to everybody. Anyway, now, I can afford to pay someone to come help me with housekeeping a couple of times a month. I'm also disabled and can't handle it myself. So once again, money is everything.

Even if I reached a point where I was so wealthy that money didn't mean anything, it would still be everything because I would still need it to be paying all of the people who would be helping me.
