Yeah but one half went to college

And then they sat through 2-4 decades of Democrats actively voting against the interests of their constituents, ignored it, and vote for them anyway despite the evidence right in front of their eyes.

Democrats aren't our friends. They stab us in the back while Republicans stab us in the front.

I would argue that those who graduated from the school of hard knocks are why we have labor laws and unions. It wasn't college educated people who were the drive behind unions.

Strike: Strikes in the United States

The first nationwide strike occurred in 1877, when railroad workers struck in the middle of an economic depression. With the advent in the 1880s of such labor organizations as the Knights of Labor and the American Federation of Labor, strikes became more frequent. Some of the more important industry-wide strikes in the United States have been those waged by the railroad employees in 1877 and 1894, by the United Mine Workers in 1902 and 1946–47, by the steel workers in 1919, 1937, 1952, and 1959, and by the auto workers in 1937 and 1946. Important local strikes have included those of the Western Federation of Miners in the early 20th cent. and of the Teamsters Union in Minneapolis in 1934.

I highly doubt railroad workers, miners, steel workers, and auto workers all had post-secondary education. If it wasn't for them striking and pushing for better wages. We would be far worse off. Without better wages, post-secondary education would be a pipe dream for money.

National Association for the Protection of Labour

The National Association for the Protection of Labour was one of the first attempts at creating a national trade union centre in the United Kingdom. The organization was established in July, 1830 by John Doherty, after an apparently unsuccessful attempt to create a similar national presence with the National Union of Cotton-spinners.

John Doherty (trade unionist)

Doherty began his career as a cotton spinner as a child worker just ten years old in his home town of Buncrana...Following Doherty's relocation to Manchester, it was not long before he was involved with the factory workers' growing movement for higher wages and better conditions. In 1818 he was a leading figure in the spinners' strike and was imprisoned for two years. Rather than deterring Doherty this merely enhanced his desire to obtain better conditions for himself and his fellow workers and he continued to be an active member of the Amalgamated Association of Operative Cotton Spinners following his release.

I doubt someone who had been working since ten years old in 1800s would have any education other than an extremely basic one. Yet, John Doherty pushed to create a national union to fight for a better future.

What Made the Battle of Blair Mountain the Largest Labor Uprising in American History

Despite the ultimate surrender, one of the many bits of Blair Mountain history that continues to stick out is the diversity of the miner’s army. In 1921, coal company towns were segregated, and Brown v. Board of Education was decades away. However, Wilma Steele, a board member of the West Virginia Mine Wars Museum, says Matewan was one of the only towns in the United States where Black and white children, most commonly Polish, Hungarian and Italian immigrants, went to school together. Other miners were white Appalachian hill folk. Most all were kept apart in order to prevent organization and unionization. It didn’t work. Keeney recalls one incident during the Mine Wars, Black and white miners held cafeteria workers at gunpoint until they were all served food in the same room, and refused to be separated for meals.

Seems like uneducated coal miners were far more progressive.

I will agree that post-secondary education has been a overall boon for progressive politics and for a better society. It can be argued that the chance to get post-secondary education would never be possible if it wasn't those who graduated from the school of hard knocks. It wasn't until the uneducated working class fought for better a living, post-secondary education was allowed for those with money.
