A lack of land? Are you sure about that? I don't own land. I do OK. Why? because I have skills that are in demand in the current service economy.

You only need land if you want to live like either a serf or a land baron. There are very few people who want to live like serfs, and there is not enough land for everyone to be a land baron.

I suggest you read more than Karl Marx. But if you quote Karl Marx, you probably aren't much of a reader.
