Indeed. The so called "free market" fails to assign people the true value of their work. As I said in another thread, worthless people like lawyers, CEO's, politicans, stock brokers, and bankers are given vast wealth by the free market while the truly valuble people in a society like professors, teachers, scientists, doctors, engineers, technicians, and other skilled and worthwhile members of socieities are paid very little by comparison. The "free market" is at its core inefficent. It allocates wealth according to that which is most profitable, not that which is most valuable. In a socialist system people who are valuble would be paid more.
Thus the wages in a socialist system of doctors, scientists, phhysicits, engineers, teachers etc... would be significantly higher than the wages of a politican and lawyer. (CEO's and stockbrokers wouldn't exist, no they wouldn't have been shot even though they deserve it, but the need for them would have been abolished since the workers would democratically control the means of production and thus would be able to run their own affairs without such worthless people.)
