Proving that profit is economically and morally justifiable, rather than the result of exploitation, has been a central preoccupation of neoclassical economists.

Like a forensic accountant trying to solve a corporate fraud, following the trail of money around the circle is a good way to understand what actually happens as capitalism unfolds.

The total dividend income declared in 1995 by the bottom 9.7 million Canadian tax-filers (47% of all those submitting tax returns) was $310 million. The estimated dividend income received by the Thomson family in 1995 from its 72% ownership share of the Thomson Corporation and its 22% ownership share of the Hudson's Bay Company was $310 million.

With joint-stock corporations, investors can place bets on the success of many different companies, without having to play a central management role in any one of them. This allows investors to diversify their financial holdings. It also allows them to capture profits on their investments, without having to get involved in the dirty, troublesome business of actually running a company.

Economics is a social science, not a physical science.

Employers crave the power to fire workers whose performance is judged inferior-not just to get rid of those particular workers, but more importantly to motivate and discipline the rest of the workforce.

Economic systems come, and economic systems go. No economic system lasts forever. Capitalism is not likely to last forever, either.
