My own general explanation of why everything sucks is more like this: we don't know how to stop. The market can't stop itself from over-optimizing, over-exploiting.

The evolution of any product, service, company or technology, can be to a first approximation plotted as a bell curve:

  total value provided to society
  ^              
  |              ....
  |             ..  ..
  |           ...    ...
  |        ....        ....
  |   .....                .....
  ------------------------------------> time

The market always goes all the way to the right. What it should do, what we need it to do, is to stop at the peak of the bell curve. Alas, there is no mechanism that would get people to say, "yeah, this is the best it could be, let's go do something else"; the market demands they move to the right, all the way to diminishing returns.
