> Correct, corporate tax rates are generally regressive in their effect.

Corporations can be shell companies. Whatever rate or tax you want to be applied to "the rich" has to be at least that high on corporations or "the rich" would just put their money inside a corporation and pay the lower tax. So it turns out all taxes are "regressive" at which point you might as well use the the simple, uniform, less distortionary ones (e.g. VAT) and then achieve different effective rates via transfer payments, the most efficient of which is a UBI.

> Building jets and houses creates jobs though.

That's assuming they're building houses instead of buying up the existing stock while restrictive zoning prevents more from being built. Moreover, jobs building private jets or satisfying other hedonistic consumption are less helpful than jobs building battery factories or growing food, even if they did employ the same number of people.

> A more likely outcome of a consumption tax is that wealthy people simply spend less.

The reason wealthy people don't spend most of their income is that they already buy whatever they want and then still have money left over. Bill Gates isn't going to buy an economy car instead of a luxury car over a sales tax.
