Jeff Bezos got nearly $300,000 to start a small online bookstore that was statistically unlikely to succeed (most small businesses fail within their first years).
In stark contrast, the yearly median American income is $31,133 while yearly median rent is $21,924, average food costs are $6,600 per year, and average clothing costs are $1,932 in a year. This means that an average worker can have leftover wealth of just $677 per year; it would take over 400 years of working for an average proletarian to amass enough wealth to start a business like Bezos did.
For surplus-value extraction, we can see that the average CEO earns $20,000,000 per year as compensation. Compare that to the average worker’s income that is little over $30,000. The CEO earns more than 600 times as much as the worker, even though a CEO’s labour is not much more skilled, intense, etc. than an average worker’s.
