Democracy and socialism
A major difference between democracy and socialism is the free market principle which allows buyers and sellers to agree on price without government interference. Democracy, a political system which promotes individual initiative, generally supports free markets. Socialism in most of its forms interferes with individual initiative. Despite this, however, several adherents to Socialism see Democracy, specifically pure democracy, as being at the very least a tool to implementing socialism if not outright being one and the same with it. Karl Marx, for example, once declared that "Democracy is the road to Socialism", and Vladimir Lenin likewise declared that "Democracy and Socialism are inseparable."
Democracy and socialism are both political systems, although much of socialism is more concerned with the economy. Marxist countries have created socialism which transcends mere economics by combining a political despotism which enforces atheism.
