Surplus labor is power to those in power. Scarce labor empowers the individual. Compressing demographics is good for the individual, but bad for economic and political systems.
This is true to an extent but we have never really seen an information economy with a global labour scarcity. If we look at "advanced" economies with physical labour scarcities we see infrastructure deficits and inflation in asset prices.
Having worked behind a computer and behind hammers, saws, on ladders, et cetera I think that political/economic collapse might not be ideal. With that said perhaps my socialist history teachers couldn't overcome the immense power of British propaganda against revolution.
If current state is a form of economic slavery, alternatives may be welcome. Depends on your point of view I suppose, as well as your role and position in the system. Some may welcome decline over current state and the cost it imposes.
