Who knew that the primary incentive being economic would lead to a convergence of human behaviours?
Every profit-motive champion raved about the variety produced by means of competition. Instead, the fear of failure from truly distinguishing oneself has driven competitive differences to the edge where it remains superficial and unimportant. Alpine white or cream white paint? Straight tube or spherical Edison bulbs? Nietzche or Camus on the toilet bookshelf?
In fairness, we can say that this incentive has normalized a lower bound of acceptable design in terms of function. Yes, it's bland, but it works.
But now what? The incentive needs to be transcended. The only way to do that actually is to be rich and/or crazy enough to deny the potential of economic failure. But who can afford to do that?
This hasn't changed. The Sistine chapel wasn't painted according to the whims of the peasantry.
