I would strongly disagree with any kind of arbitrary cutoff line.
I think there are two related points about income inequality that need to be addressed.
First is the argument about standard of living. I think that in a prosperous modern society like ours, we have a responsibility to ensure that all members of our society can have access to basic necessities - food, shelter, healthcare, education, etc - regardless of income level.
Second is the argument about undue influence over society. That one is tougher because while you can try to get money out of politics, the ultra wealthy have other ways to influence society. Owning media companies, for example, or social media sites. I think that in those cases, what we really need is regulation. TV and radio were heavily regulated because the air waves were a limited resource with an impact on the public good. The internet or cable TV aren’t limited in the same way, but they do impact the public good, and we must find ways to regulate them to stem the tide of misinformation.
As far as billionaires themselves… We will have to tax them more heavily to pay for a robust social safety net, and that’s good. We should be regulating them and their companies, to protect public welfare from externalities and bad actors, and to prevent anti competitive practices that prevent the market from functioning. So long as all that happens, I have no particular objection to someone amassing billions.
Adopt a page or two from the Mob: “You owe $2 billion in taxes. You’ll sit in this prison cell until your attorneys deliver the funds to the Treasury. What’s that? It will take months to liquidate slowly enough to get any return at all on your money? Sucks to be you. BTW, dinner tonight is Nutraloaf.”
Obviously you don’t know the first thing about concealing wealth. Mr. Moneybags doesn’t owe $2 billion in taxes because on paper (according to tax law) he doesn’t own anything and hasn’t earned any taxable income. So what are you taxing him based on?
Wealth tax. “The paper value of all assets that can even remotely be tied to you is X. Pay us Y.” If they flee the country or try to conceal their ill-gotten booty, confiscate everything they’ve touched and exile them forever.
I would also like to see some kind of intervention in the passing of wealth between generations. It’s one thing when a person is a multi-millionaire because they built up a business. But I see less justification when a person is a multi-millionaire because their grandfather built up a business.
I wouldn’t prohibit the intergenerational passing of money. But I’d have a large inheritance tax kick in. Let’s recycle some of that wealth back to the other ninety-nine percent.
Not to bash too heavily on the mega mansions themselves. True, some tourist money is brought in by bottom-up attractions like the souk in Istanbul or those amazing rice terraces in the Philippines. But the big bucks come in, albeit unintended by their top-down originators, from attractions like Versailles and Biltmore.
And it wasn’t some capitalist artificial-scarcifier who said “too many useful things result in to many useless people.”
What’s unrealistic is the idea that this would somehow improve the lot of the working and middle class, rather than putting us on the sort of trajectory that Russia has been on this last century.
So basically you have a lot of people with mortgages and school loans and credit card debt working for the 1% (or by extension the financial services industry) through interest on their debt obligations, whether they realize it or not.
