Or maybe the solution is to remove the political (dis)incentive structure such that the will of an irrational population doesn't continue to cause harm.
So, we have the will of the people. So far, so good.
And then we have the complete freedom of capital to nudge the will of the people.
Something is wrong with this picture.
Seems even if you remove the influence of capital, you're just kicking the can rather than actually solving the problem.
"Nudge" is far too weak of a verb, here. There are many structural issues between the population and exercising their will, and many structural advantages that allow capital to exert undue pressure on the political process. These advantages and dis-advantages are inherent to our system and have been described at length in academia.
