Well arguably, like it or not, capitalism has been the single largest economic force behind millions being lifted out of poverty and into the middle class world-wide. Globalism has only helped this. So one could say that capitalism is the current "greatest" ideology. Therefore I would amend my argument as claiming that Marxism will never be the greatest ideology in comparison to capitalism.

If you want "free" everything and a gulag for dissenters please leave our fine country.
