A lot of this. I vote against what are perceived as my most direct/immediate interests. I could have more money in the bank at the end of each year if we lowered the shit out of taxes.
But in terms of long term, expansive interests, fuck that. It's in my interest to have a stable and prosperous country going forward for my children and grandchildren (although the jury is out - my kids may have already "noped" out of here). It's in my interest for my neighbors to do well, to be stable, safe, and secure. People like that participate in their communities and commerce, fueling our social and economic engine, which ends up benefiting me. Educated people are less likely to commit crimes like stealing my car and such, which also benefits me. And the list goes on.
An approach of gathering as many dollars in your own pockets, no matter what the cost to everyone and everything else (and mind you, the MAGAs aren't even accomplishing THAT - except for the absolute richest of them, they didn't get richer under Trump) is utterly destructive and counter-productive -- having lots of money in a hellscape means you're still in a hellscape. Check out the people with nice houses and money in places like Honduras - I expect most of them would much prefer to be middle class here in the US, where they don't have to top their walls with razor wire, burglar bars, tall locking gates, etc., where they can safely shop at the grocery store or mall, all that shit. Having a functioning society around you is one of the most important factors in prosperity.
