The market was not allowed to correct in 2008. Obama did what he could to stop it from falling apart... but it could never be stopped. He delayed it... he kicked the can down the road. And that's the point that was missed in 2008. People think we fixed it and that we all recovered and everything was fine... we didn't. This was always coming down the pipe. The federal reserve was never able to get to a point to raise interest rates back to a healthy level. That was the primary indicator/marker that nothing ever got fixed.
We didn't swallow our medicine in 2008 and let the market correct. We tried to intervene because we didn't want to deal with the problems. And no doubt, we did lessen how painful 2008 was... for a short time. We made things feel and seem better. But we didn't fix it. As I said, this was always coming. We should have dealt with in 2008 and let the market correct. Say it with me.
Anyways... Obama blew the bubble way up. Trump blew it up even further. They're both at fault and if you can't admit that it's because you're naive/blindly partisan. And too much power is put on these guys' names. It's the federal reserve and the entirety of the Untied States government. It's not as simple as 'but hurr durr Clinton/Bush/Obama/Trump.' It's demonstrably more complex and nuanced than that.
