Serious question: if every company was working with razor thin margins, and every worker made make minimum wage while investors reap profits from speculation, would that be good?
> in the case of the GM stock particularly, are shareholders/investors reaping profits and benefit? go look up the GM stock, it's flat/down over 5 years
You failed to take into account that GM issues real stock (unlike most tech companies) and thus pays dividends. If you take dividend payouts into account, the value of an investment in GM has been indisputably positive (though probably not more positive than inflation).
