I believe the primary cause for wealth inequality is political campaign contribution laws. These laws allow Congressmen to take bribes (political campaign contributions) from rich people to pass laws to allow the super-rich to “legally” exploit the middle- and lower-economic classes and legally “extort” their productivity.
Over 90% of the American people are “sensitive” to the idea of wealth inequality and agree that the inequality is wrong. This implies that wealth inequality is going to be a huge political issue in the near future. The political impact probably won’t be felt in this year’s election. But if there’s no real economic “recovery” in the next two years, come A.D. 2016, this issue could be decisive and even explosive. Although both political parties are guilty of taking bribes to enrich the super-rich, wealth inequality is an issue that could damage and even cripple the Republican Party in A.D. 2016.
