Accomplished

Did capitalists think for a second - what if when they made all state property theirs? How do they increase their piece of the cake still then? What do they want to put on top of that? Going to space?
What if discovering and exploiting space still is impossible? What if if you have to be content with the resources you find on the earth?
What if if you can't go to the depths of the ocean if there are still no technical means for that business, or they overstep the profits you wanted to make?
What do you seriously do if you have conquered the last area, the last territory on earth, to increase your stack of richness that you have?
