The fact is that the ability to succeed beyond our wildest imaginings has always stood as an incentive for Americans to strive to better themselves. People have come to America from all over the world to achieve the same dream. Unless you are an American Native, your ancestors were among them. The success of their casinos tells me that some of their incomes also are a lot more equal than mine.
The fact is that income equality doesn't work and we don't have to go very far to see the proof. Look back in our own history to the arrival of the Pilgrims. Before setting foot ashore at Plymouth, Massachusetts, they signed a contract, the Mayflower Compact, establishing rules for their new community. Central to this agreement was a plan for common ownership of all property and the fruits of all labor. All crops and goods were stored in a common warehouse to be doled out equally to everyone. It was, in effect, absolute income equality, and the community failed.
You probably were taught that the Pilgrims were saved by the Native Americans whose land they stole. Sadly, I was taught the same. The truth is that a significant majority of the native peoples died of disease long before the Pilgrims arrived and the Pilgrims saved themselves by abandoning income equality. Once individuals were allowed to seek their own fortunes, they produced surpluses that they could trade with their neighbors for the things they needed. In other words, capitalism saved the Pilgrims.
In much the same manner we see populations all over the world enjoying the fruits of their own labors. Healthy populations of middle class citizens are growing in India and China, albeit in limited enclaves in those countries where capitalism is allowed. Meanwhile, the middle class is shrinking in developed nations where it once thrived, such as England and France with the advent of social democracy, and now in the United States under the aegis of progressivism.
So, why are the Democrats pursuing a crusade against income inequality? It seems likely that it is nothing more than a smokescreen to obscure the failures of their most progressive programs such as Obamacare. Don't be fooled by it.
