Capitalism can cause greed when capitalists (owners/shareholders of companies) do not reward labor, which produces the goods or service, with an equitable share of the proceeds. One of the statistics Get Human Foundation highlights is the alarming wealth gap that has been created within the current structure. In 2011 the wealthiest 400 Americans owned half the wealth of the United States. It can be assumed part of their wealth was accumulated from business ownership, either through profits or upon the sale of the business.
If employees (labor) of the companies had better pay or had more of an interest in the company (equity), the wealth gap would not be so large. If rules limiting executive pay and yearly return on ownership are foundational law , employees would be quite a bit wealthier, contingent upon owners being willing to share the fruits of everyone’s efforts.
The current debate over people returning to work is an interesting one. Public servants (our government) state there are plenty of available jobs but not enough labor force to fill them. Supply and demand dictates in free-market capitalism. Jobs that are listed at the pay (reward) mentioned and/or the type of work offered are not in demand. This system does not cater to all specialization and education levels. If the businesses placing these employment ads paid more, they may get their needs met. The supply and demand curve points this out nicely. The government is forcing people to take jobs that do not pay enough to live a modest lifestyle. Capitalism establishes a pattern which unfairly distributes equity.
