Labour is the source of all wealth, the political economists assert. And it really is the source -next to nature , which supplies it with the material that it converts into wealth. But it is infinitely more than this. It is the prime basic condition for all human existence, and this to such an extent that, in a sense, we have to say labour created man himself.
– Engels (1876)
