The underlying risks to "prosperity" are very real, but are primarily global in my opinion—climate change, other forms of environmental destruction, advanced and destructive weaponry, mass human displacement, and the threat of a stable, horrible life of servitude under the authority of global capital.
The condition of "dominance" or simply freedom, agency and self-actualisation is a result of political and economic power, which also subsequently leads to a relative gulf between material lives. That power is slowly being whittled away from the publics of developed societies, I believe.
I think about the 70m "service workers" so underrepresented in the recent US presidential campaigns when I ponder whether things are actually going well. The life of a worker in an Amazon fulfilment centre is worse than that of a preindustrial peasant.
Humanity has charge of far greater productive forces than at any time in history, but we will have to fight to see them used for our collective betterment in a sensible way.
