But yeah same is true for income tax, my country has a really high wage income tax at top bracket (close to 50% with health&benefits) that kicks in really fast, but profit income tax caps at 20% because people would just take profits out of the country if it was higher. so a lot of people work around it by invoicing their salary as self owned company pay min wage and take the rest as profit.
The profit out of salary (for most people) is just not big enough to justify an accountant to optimize.
There is a lot to be said about replacing income tax with a pure consumption tax (it is one possible financial model for the universal basic income).
Most systems tax these at a higher rate. See e.g. https://en.wikipedia.org/wiki/Fringe_benefits_tax_(Australia...
Wouldn't the same argument hold for income tax then?
I mean, I can evade income tax to a certain extent by making my boss buy me a nice car, computer, bicycle etc.
