What do you mean when you say "scientific"?
Well, the argument in your first paragraph is somewhat compelling. I heard the view that the service economy can grow regardless of natural resources, but I suppose you would say to that that it is only possible in imperialistic countries that move industry elsewhere.
I will think on the matter, and maybe come up with counterarguments. I am not an economist, so the finer details of markets are eluding me. In any case, Marxism or not, let us hope for a few more decades of decadent bourgeois life.
I enjoyed our converation, it is more fun arguing with people on the internet when they are not idiots.
But I wonder, do you consider maths a science? Also, there are practices thay deal with practical matters and "the real world" that are not scientific. Like natural philosophy. I think method and rigour are more important than subject.
