I mean, it's not just boomers, because it's a world wide problem. But in general inequality is more or less the biggest problem. After every financial crisis birth rates drop and stay down.

All graphs realted to inequality and general quality of life have been steadily dropping since 1971 when we introduced the FIAT money system. Basically ever since then the entire system is set up to steal from anyone who can't benefit from debt and give that money to those who can. Any savings and income is constantly eroded away steadily making the bottom ~80% poorer. Then we also started artifically lowering interest rates, which made the stock market and real estate markets go nuts, making everyone who already had assets rich and those who didn't even poorer.

Boomers didn't really cause this, they have no idea what any of that even means, they just passively benefited from it, because they already had assets. It's more or less created by a tiny policial and financial elite conspiring to takw over our monetary system in 1971. The entire financial and monetary system were reengineered to benefit the rich.

Mark Blyth frames it as a revolt of capital in his book Angrynomics. Basically before that workers benefited hugely from the system, because wages were constantly rising in line with productivity growth and cumulative inflation was so low that you would actually save. There were no crazy real estate bubbles created by the central bank like we see today. That stopped after 1971.

I wouldn't say Boomers did this, because they were way too uneducated to even notice what happened, because they got all their news from the same people that stole their children's future. You can blame them for being to stupid to stop it, yes.

There's some other factors too, like people moving to cities and social issues, but inequality is one of the biggest, if not the biggest. It's pretty much clear as day in the data if anyone cares to even look. It's not some big mystery, it's just going completely ignored, because it would be a huge problem for the people in power.

Oh yeah, and the reason why this problem is world wide is because we exported that same system all over the world to pretty mich every country on earth. Ghadaffi wanted to break that system with an African stable gold backed currency and that's why Libya was destroyed. It would completely invalidate our imaginary money like the Dollar or the Euro and the powerful couldn't steal from the rest of us every single day.
