Over at Town Hall, John Hawkins has a thoughtful piece on the subject which points out that the term itself is essentially meaningless.
But even beyond the points John is making, Democrats act as if there is something inherently evil in the idea that some people have more than others, whether they earned it by dint of their own efforts or inherited it. Can anyone justify that in an open society founded on capitalist principles? In the end, America is supposed to be a place where everyone is assured equality of opportunity, not equality of outcome. When we find areas where people are being denied opportunity we should correct that, and the government can do much to ensure that the greatest opportunity possible is made available. Sadly, the socialist tenets of the Democrats seek to do just the opposite, robbing the rich to give to the poor with little concern for whether or not that generates disincentives regarding productivity and ambition. If you want to fix income inequality, fix opportunity equality. And that means more jobs and a chance for people to save and invest their earnings rather than giving them all back to Uncle Sam.
