Taxes

I don't mind them at all. In a civilized society, they're not a problem. They are, in brief, the price the individual pays for being part of that collective, for maintaining the framework and structure of that civilized society. It makes your schools, hospitals, roads, railways, bridges, ports, wilds*, and plenty more besides.

No small number of Americans just... don't really get that. They think all the money just goes into other people's pockets. (To be fair, they're not completely wrong. There is a degree of waste in U.S. governmental spending, but it's never in the places most people bitch about.) Another problem comes with the taxation system as it exists. It's needlessly complex by design, creating a problem specifically to more readily sell you, the citizen, a solution: Pay Someone Else To Do It. (Apropos of nothing, fuck you Intuit.) Wouldn't be inherently bad except for the all-encompassing flimflammy ethos of American "self-reliance". Those concepts are at cross purposes, leading the LCDs to get confused. And when people are confused, the easy solution is simply Pay Someone Else To Sort This Out- and there goes some of the hard-earned money. 

Instead of a system designed to be simple, efficient, and effective, it's deliberately difficult. It results in a fully fabricated field of finance, largely loopholed into irrelevance by those with wealth, widening the gap between the Haves and the Have-Nots. The richer you are, the easier it is to avoid having to pay a valid and acceptable share of taxes. On top of that, many administrations' worth of government have actively hamstrung things like the IRS specifically to make that problem the norm- largely due to the ease of fostering influence between money and power.

Get the thousand wealthiest American citizens to pay a fair share of the tax burden, and cut the tax code down to size. That's a solid place to start.

*Yes, even the wilds- Humanity has cemented itself as the most intrusive and harmful impact since... Chicxulub, give or take. Got to do something about that.
