I thought about this paradox myself and later found that Adam Smith already
thought about the same.Although I don't know to what conclusions he came.
For example in some country all businessmen combined pay to all workers combined one trillion of dollars as salaries a year.After that businessmen sell their
goods to workers and expect to receive profit.(Lets don't take import-export in account.)And expect to received profits.But all worker combined could return to all businessmen only what they being paid-exactly one trillion of dollars.Where profits come from?Could somebody explain in details how this issue regulated in
modern developed countries?
