Regarding the Zumwalt, Ray Mabus thought that the Zumwalt class would be a capital ship when he was SecNavy. So, he named the second ship of the class after a President, just like a carrier (i.e., a capital ship), which is something he verified in person a long, long time ago when I was a different kind of person, someone who had conversations with these kinds of folks. This has turned out to be something of a sick joke, unfortunately.
Regarding defense spending, it's a necessary evil -- or do you really want Beijing to be telling you how to live your life, and enjoy a patriotic education glorifying Mao and Xi? To me, the military is like the police -- you really can't live without it. That being said, you don't need to bend over backwards for the military-industrial complex all the time, the US should be BUYING weapons systems from overseas manufacturers if you'll save 2/3rds of the cost. At least it will limit the avarice and rent-seeking of the domestic monopolies.
Regarding progressive income taxes -- beyond what I've written above -- it's hard not to say that the wealthy and well-to-do have benefited more from a stable society than the less well-off. Shouldn't you pay for what you get? Who has more to lose if the government collapses, at least in dollar terms? It should be that the billionaires pay the most by far, the well-to-do pay their fair share, and the poor pay little if anything at all.
Speaking along these lines, if we didn't have such massive economic inequality, we also probably wouldn't have the madness that is MAGA-land. An old colleague explained to me once that MAGA was originally triggered by the bankers getting off scot-free after the 2008 recession, when they lost gambles they made with public money. If we had fewer folks that were having such a rough time and also, fewer folks who are living in mansions and have multiple yachts, we'd have far less polarization. Perfect examples of countries that very much look like the US except for having less inequality and less crazy politics are Canada and Australia. If I were super-wealthy, having a stable society would be worth a great deal of money. Yet, the folks I know who live in mansions don't seem to think this way -- they think that their taxes are too high.
I'm not beating up on you, Saucy, since you're carrying huge amounts of student debt.
