> Without society it's pretty hard to be well off in the first place.

What a pointless argument - you could just as easily chose cause and effect in the other direction: without businesses then society has nothing. Zero businesses, zero tax income.

My main point is that society needs to encourage business owners. If marginal tax is too high, then owners have no incentivise to earn themselves an extra dollar. When owners earn less then society gets less.

There's a balance to incentives.

I'm not working currently because my taxation rate is too high. I'm fine with that since I value my time highly. However financially my country could be getting more from me by lowering my taxes enough to encourage me to work. But voters don't care about what is sensible - they care about optics - and politicians care about voters more than they care about the economy.

I find this softer position much more amenable than your GP comment.

However, you conflate "businesses" with "entities that pay only some minimal poll tax". It turns out that progressive tax does not preclude complex society. Corporate tax does not kill business on touch. All you've argued for is the existence of the Laffer Curve.

Commercial activity predates currency, and is omnipresent across every tax system that has ever been tried. Where money, there trade. Where trade, there value-add. Or at the very least, combing the beach for pretty shells.

There are tribes without the concept of personal property or money, that make things and build value. No tax can extinguish human creativity.

I'm cagey about secondary effects, but I'm cautiously optimistic about debasing the trait of self-enrichment. I see no reason to take on faith that people acting out of self-actualisation would build a lesser technology. You know you're on a site full of nerds, right?

The existence of the internet protocols is a case in point.

Conversely, I prefer a world without facebook and robocalls.
