because in reality pie can grow only so much.
virtually all the resources from oil, food and land, IP and tech (semiconductors), even human capital, and advanced IT. everything is captured already. from free laisure entertainment minutes, to internet search, to social. every single resource is captured and you are stepping on somebody toes. worse, most industries are monopolies/or-close, meaning couple whales dominate everything, and nobody else really matters.
whatever "new" pie comes out, it is usually at expense of something else.
this "creation of pie" is such an illusion. go and try to "create a pie". it is such an illusion.
just go and try to even grow food out of earth with sunlight and water (which all should be free), yet farmers notoriously unprofitable and would not survive without government subsidies.
