you see all around the world that communism has failed.
so why should it still be around?
I think that's a little myopic. Bear in mind that it took hundreds of years for capitalism to be established throughout most of the world. Russia and China (some of the biggest countries in the world) only really became capitalist last century. Capitalism arrived in America only 500 years ago. Before that it was only kicking around England, Holland, France and Germany in minor ways.
Just think what serfs, artisans, clergy, yeomen and the aristocracy could have been talking about before then?
"Ha! This waged labour thing, it'll never take off! Why would I want to work for someone else? I have my own land that gives me life."
or "Why would I rent you? I own these guys."
or "My sole purpose is to serve my master."
Fast-forward 500-700 years, you get America and African slavery, the enclosures, Dutch->English->French revolution, the colonies, massive militarisation and world wars, etc. etc. It's totally hip to be a waged worker these days. Almost everyone's doing it. It's the first fully world religion.
In comparison, how long has been communism been kicking around? 200 years, more or less. Sure, the trend is downwards, but history isn't a progressive line. I wouldn't write it off just yet. I think it is wise of FD to retain it, even if it's only in the form that we've seen established last century.
