Going with the other issue: unemployment at least has some legs to stand on as it has been suggested that there just aren't enough low skilled jobs for all of the low skilled people to do since most low skill work has been either automated or increased in efficiency to the point where 1 person can do something 1000 used to do.
If history has taught anyone anything, it should be that civilizations are not static. I very seriously doubt that democracy and capitalism will be the predominant foundations of society 1,000 years in the future.
When will the "next big thing" come? I have no idea, nor does anyone else. But to say that there are no alternatives to capitalism, and to imply that there never will be, is shortsighted.
like I said before, the alternative to a free exchange of goods is a forced exchange of goods. I don't see how to improve on this. capitalism isn't a system in the same way socialism is. It's just what naturally happens when violence is made less profitable than free exchange.
Capitalism vs. socialism is not an example of free exchange vs. force, but of two different standards of when force is appropriate.
This would be a devastating argument. If I had a choice in the matter. In a free market system of courts and transportation I would pay a fee for use. This is fair. But to tithe a percentage of my productivity regardless of how much or little I make use of said system seems fraudulent.
I also don't understand the term 'contrary to reason'. How can a set of conventions be rational or irrational? They can be beneficial, harmful, fair, unfair, moral, immoral etc, but how can they be contrary to reason?
Also: taxation is as much a part of capitalism as it is a part of socialism, especially taxation for expenditure on police and law.
Capitalism really is a bad term anyway. Marx invented it so he could use it for his straw-man arguments. But really it should be called free markets, or freedom, or opportunity, or the American Dream or something.
