An issue I always have with early retirement is whether it is morally acceptable. When retiring early from a skilled profession you are depriving society of a big contribution you could have given, that was also expected and invested in by society. Utilising a power dynamic by having more money and knowledge to capitalise on other people exacerbates this issue.
How are you dealing with this? Are you of the mindset that you do not owe anything to society? That it is completely fair, as you earned that money and there is a perfect market that trades all aspects in a meritocratic fashion (e.g., delayed consumption should be gratified this hard)? Or that you were not just lucky to have the talents to earn so much money?
I mean if you have enough money to retire early you have by the definition of capitalism provided more than you are taking by retiring.
Whether it’s moral is entirely separate, and would require judgement outside the confines of capitalism, which is not possible, because we don’t live by any other system.
