13th century peasants didn’t live a much better life than many people did 100 years ago.
But even if you’re only talking about the US between the 80s and now, you’re still wrong. Unemployment is half of what is was in 1980, and at the lowest rate since the 60s. Household wealth has grown an enormous amount since the 80s, the poor are less poor and the poverty rate has dropped since the 80s too. The only somewhat legitimate issue you can point too is that housing in some areas is unaffordable for most people. But if your biggest complaint is that you can’t afford to buy your own house in the most expensive cities in the world, even though there’s lots of places where you could, and even though poverty and unemployment is down, and household income is up, then maybe you’re just proving my point?
