Depends on the field what you risk. Many white collar jobs will not risk their lives or injury, plus nowadays regulations should reduce these extreme risks.

Saying "owner simply has less money" can have many implications on their life. If they choose to put money in a company rather than have a bigger apartment/TV/car/whatever, I find it fair for that to be rewarded a bit.

I think it is disingenuous to think "basic needs" is simple to define, considering that there is no cheap and free energy source (and other resources). For someone living in a warm climate, the basic need for heating in north of Europe will look like a waste.

My opinion is that tax systems are completely outdated and they should use more "asymptotic/exponential/complex formulas". Sure a tax of x % on profit worked 100 years ago when most people were "closer" but with today's growth (of many things), you get too much concentration. But of course that would imply that people understand both tax and math, so most will not demand it.
