Having started companies in Norway without being rich at the time, it's not generally remotely a problem. The wealth tax is low, and it only kicks in over a threshold. If you can't afford to have your company pay you enough or lend you money to cover the wealth tax at the point where it starts to become a challenge, then your company is likely a shitty investment.
There can be extreme corner cases where it's a challenge, but it's extremely rare.
I don’t support these kinds of taxes but I think that is also a little hyperbolic.
Poll taxes, and even flat taxes can also be seen as unjust taxes on ‘money you do not have’ when you subtract the cost of life from someone’s income.
This one is novel in the modern era because it only substantially negatively affects capital owners, rather than wage / fixed income earners.
As both capital owner and wage worker though, I just see it as yet another potential headwind… and yes, there are class dynamics at play that go beyond the economy and up into political power and the state.
