Fulfillment comes from positive human interactions, a sense of community and place and belonging in the world. Capitalism eroded everything certain about society and replaced it with a race to the top. It has been incredibly productive in producing a greater and greater volume of things, but in terms of fulfillment and happiness? I think that metric is at least debatable. The paradigm of unlimited growth is also killing the planet, as with the increased production comes enormous quantities of waste and pollution.
With the increase of choices in the market, whether the physical market of things or the memetic market of ideas, there comes a great deal of anxiety. Each choice is also a loss of the other choices, and then you add in social expectations into the mixture and suddenly choices seem a lot less liberating.
Reducing a human being into a commodity themselves is obviously not going to produce happy, fulfilled people. To restrict oneself to the neat little box the market would have us be is to become a robot, a fully automatic man, a cog in a grand machine producing wealth for wealth's own sake rather than man's benefit.
Don't get me wrong, the electricity and the roads are great and all but I think at a certain point things have gone horrible eschew, the whole modus operandi has outlived its usefulness if the goal is human thriving.
