I only know of two ways a monopoly can actually exist for long.
- They are doing such a good job no one tries to compete, and no one cares they are a monopoly
- They have a government exclusivity deal, or have convinced the government to block attempted competitors.
It is sad how many people bash the market without realizing the thing they are actually angry about wouldn't exist in a free market. It requires government interference.
EDIT: And yes I posted on the wrong account and did not respond to you in some poetic prose. This is an out of character moment.
