Can one become rich as a salary earner?Without other or additional means of income, and without corruption?
It depends on their salary. Professional athletes, for example. Sportsmen make more money on average than people who are income earner. But sportsmen are not generally earning a salary, but winning prizes and income from participation, practice and honorariums.
That's right, athletes get rich not from their salary but from the tournament prizes they win...
In addition, most of the painting, music or sculpture artists do not get rich from a monthly salary but from the sale of the work they create.
