Actually, a lot of those "persistent problems" are not real problems at all. Like the "national debt" issue Republicans raise against Biden's 3.5 trillion dollar infrastructure bill. That just happens to be about the amount of the GW Bush and Trump tax cuts for the rich, but suddenly we can't afford spending that much on things we actually need? And it not like we are just burning the money (or giving it to rich people which is functionally equivalent): We would get stuff we need with that spending.
Illegal drugs can only be "solved" by treating drug addiction as a medical issue. The legal system is totally worthless. It's like trying to put in a screw with a hammer.
The immigration "problem" is not a problem at all! So poor immigrants want to come here and do our crappiest jobs. Okay, let them. There, "problem" solved. We need somebody to reroof our houses, mow our lawns, and wipe our butts in the old folks home. Our kids are certainly not going to do it. My mom was racist as hell until she went into elder care. Then she told me she loved her Mexican girls who took care of her so well.
