Well, the problem is that America's 1% has been soaking up so much profit, and giving so little of it back in the form of taxes (that don't immediately get returned to them as military spending and corporate giveaways) that we've been unable to spend anything on infrastructure for the last 40 years. And now it's all falling apart.
So we can continue giving the richest 1% every extra cent, and let the country fall apart entirely. Or we can finally start taxing them and making them pay for the infrastructure that they use kre than anyone else. Or we can go deeper into debt to make the repairs and updates that are so sorely needed.
You and I both know that we aren't going to suddenly start taxing the rich, because they own all the politicians that would make that happen. And we can't just let the whole infrastructure system fall apart, because even the rich would suffer from that. So we're going to do the only thing that's left: we'll continue borrowing, and increasing the debt, because our government is too corrupt, and the 1% is too greedy, to do anything else. The big surprise, this time, is that it's the democrats that will spend us into debt and then hand all that debt to the next republican administration to deal with, instead of the other way around, which is how it's been done for the last 40 years.
