Is making money from the labor of others wrong?

[zoidberg]

This is in related to distribution of wealth thread (http://www.democraticunderground.com/discuss/duboard.php?az=show_topic&forum=104&topic_id=162363). Some posters have expressed that it is wrong for people to get rich off of the labor of others. I'd like to explore that topic a little further.

When a bank makes a loan, an individual buys a share of a company, or an entrepreneur opens a business; they are potentially going to profit from the labor of others. A bank makes money from the interest that eventually has to be paid by somebody's labor. The value of a security is at least theoretically linked to the profitablity of a company - a condition that requires somebody to labor. A smart entrepreneur will only hire an additional employee if that decistion will be profitable. All these are cases of people profiting from the labor of others - and they are all essential to the functioning of our economy. So theoretically, why should people getting rich off of the labor of others wrong? When I worked in the private sector, I knew that people were making money from my work. That was fine by me because if they weren't, I'd be out of a job. So why should I feel guilty because I want my stocks to increase in value?
