The competitive nature of capitalism drives innovation, that's a fact that you cant argue with.
Any competetive environment will do, it doesnt have to come with a system to concentrate wealth in the hands of the few.

It took me a long time to escape the matrix, too.
This book gave me an idea of why, to be an anarchist, i had to denounce crapitalism.
