It is a wealth-sharing problem as well. I don't know much about stripe, but think of Bezos as a pretty good example - to a O(n) rounding he has 100 billion dollars and 1 million employees.
Why is he getting 100,000 from each employee ? Not because those employees send him a cheque. But because of particular outcomes of share capital, and corporate law. Decisions made in UK / US legal circles since before the USA was a USA.
These decisions have been part of 200 years of the most phenomenal growth in global human wealth ever, so there is a lot of baby in the bathwater. But look at say the German mittelstand - a different approach to local business banking. And compare european social-democracy to US welfare states.
There is a lot of room and flexibility between "totally dampen growth and human innovation" and "more equal sharing of life's burdens".
Oh and lest we forget, it is in the main scientific advances that have bought us the last 200 years, not founders or entrepreneurs, and those advances were funded almost fully by government out of ... tax revenue. So the last 200 years of growth can be seen as a story of government funded and directed scientific achievement, given reign to rollout in a benign business climate, and the workforce provided via mass education and health programs, all of which funded by taxing the successful companies.
Is that an over simplification - hell yes. But so is "young founder has great idea and works hard".
