Imagine this:
person A has no money and is working 50% of his time to get paycheck, rest of his time he uses to sleep and be with family. 100% time used
person B has money, and can hire other people to do job instead of him , and he gets his own cut, therefore, he earns money without wasting time to do so, allowing him to spread his business more and more, earning more, and with no time wasted on actually doing anything.
there's also a word for this ; modern slavery.
