Also in the DC universe, the equivalent of Lockeed-Martin is Wayne Enterprises. There's stories where Bruce is conflicted in making weapons, but nonetheless, his fortune is built on the military industrial complex.

Underfunding the government through tax cuts makes corruption more likely. The richer the rich are, the easier it is to manipulate the government for them. Why do you think so much money goes to Lockheed Martin? Who gets government contracts isn’t chosen at random, there are moneyed interests involved.

If the income tax graduations are steep enough then the billionaire class will optimize to minimize taxes by reducing their own income in favor of reinvesting in their business and employees. In theory. In reality I'm sure they'd find some way to squirrel it away while their employees apply for and get denied food stamps.

You're assuming we'd stop at Bruce Wayne.

The same people willing go after Batman are willing to go after Lockheed-Martin and every politician they paid for.

I think pretty much every study even made has shown taxing the rich and investing in the public reduce crime rates and poverty. It's the reason the USA had a massive middle class before Reagan and has experienced massive wealth disparity today: differences in tax policy and public investment.
