Are Republicans the true Marxists?
No and your linked article does nothing to further such a far fetched notion. Republicans by and large are free market capitalists well represented by the highly successful businessman, Mitt Romney. America lost a great opportunity to hire an extremely well qualified business leader to help get our fiscal house in order.
Obama and the Dems basically see Socialism and redistribution of wealth as the solution to our economic problems. By the end of Obama's 4 years, I think we will know who has the correct approach. If the economy turns around and the deficit is reversed then I will be the first to admit that our electorate was justified in reelecting Obama. But frankly I will be shocked if it happens.
Socialism made its greatest inroads with FDR and the New Deal. Since that time Socialism in the U.S. has increased a welfare state of dependency that has undermined the work ethic on which our great nation was founded. Free market enterprise with minimal government intervention is the only economic system that guarantees continuous improvement through healthy competition in the marketplace where consumers pick the winners and losers. Government can help through prudent regulations that create equal opportunity but once you try to guarantee equality of outcomes, you have crossed the line into Communism which is doomed to failure due to human nature.
