If corruption and incompetence was the path the whole time, how do you explain the US system becoming #1 in the world? Was it a fluke and that now that we have gotten 100 years of lucky wins the luck has run out and now we have the grim reality of the US system actually being trash?
You look at FDR and how close the US population supposedly almost came to eating the elites. Around that time we finally got breadcrumbs in the form of Medicare and Social Security. Now we are seeing moves to even get rid of those programs so we are left with nothing. You can't have a society where a certain percentage is playing by the rules while everyone else is picking whatever they can on the dying carcass.
The US was part of the industrial revolution, but suffered few domestic casualties (infrastructure) from either World War. The dollar becoming the world reserve currency for oil/capitalism cemented it.
(Where Russia, Continental Europe, and China were ravaged by WW2)
If the US has a culture of people making poor decisions for their own health, exploiting systems for their own benefit, and of government bureaucracies utterly failing to achieve the ends they're supposed to achieve with no accountability (and it does), no amount of tax revenue is going to suddenly provide everyone with world-class healthcare with no concern for their own money.
I'd love to never have to deal with my insurance company again, or take diagnostics or treatments without being able to find out how much I'll have to pay. I really would. I just have zero confidence that any of that would change no matter how much more of my money gets taken by the US government.
