Today in developed countries, only about 3% of population work as farmers. Soon, only about 3% of population will have jobs — the rest will have to do something else (like be employed in the sharing economy gigs). This is inevitable, and there is no way to reverse this. Government regulations can't do anything to oppose these immense natural forces, nor they will need to.
Or rather there is a way to reverse the trend and provide the need for immense material economic output: a war. A world war — because warring parties quickly lose the economic edge in a peaceful economy, and it's either everyone's in, or nobody goes. There are no unemployed at wartime.
