I'm a socialist, a socialist reformist even but I do have a communistic goal. A class free society.
Oh, I didn't see it the first time. The problem is that you have several ways to reach your goal.
1) Hardcore Marxist - wait until the country in question industrialises and reaches full-grown capitalism. Then overthrow the government and install the dictatorship of the proletariate which has two goals a) prevent a counterrevolution b) install socialism and commence building a communist society.
2) Marx-Leninist - the same, except you don't wait for the country to reach capitalism, you just switch from feudalism to the dictatorship of the proletariat, which contradicts Marx, but who cares - Vladimir Ilyich said it's ok.
3) Anarcho-communist - these folks don't like the state, so they refuse the idea of the dictatorship of the proletariat as it also is a form of government. Instead they want to reach communism via trade unions. Now this is a shameless travesty. Call it the dictatorship of the proletariate or trade unions, it has a territory, a population and power over the population = it is a state.
4) Revisionist - these people think that elections and generally liberal democracy can usher into a classless society.
The first three ways fail at the very moment the dictatorship of the proletariate assumes power. Altough it is supposed to be a dictatorship of the whole working class, an actual individual dictator emerges (after an optional phase consisting of oligarchy and elimination of fellow oligarchs by the future dictator). Lord Acton's dictum tells us that power tends to corrupt and absolute powers corrupts absolutely. An absolute dictator seldom steps down on his own will and almost everytime such thing happens another dictator will gladly substitute him.
The fourth way will fail in the long term. People won't give up private property and even if they did in a sudden affection, they would reconsider later. Sure, you could oppose the restitution of private property by force, but then you wouldn't be a revisionist anymore.
There is no point in discussing the idea of classless society itself as there is no way to reach it.
