By alenating capitalism are you perhaps referring to reaching FIRE and sitting at home all day watching netflix or permernantly travelling not doing any sort or form of work? The FIRE community does define the retirement part very differently as compared to traditional retirement ideas. You could set up a company with no worries on maximising profit and the undue stress because you have to support your family and cannot afford such risks normally. why shouldnt people by striving for FIRE. even if they do not end up reaching that level, their financial health would be in so much better shapethan previously. I believe theres no fixed way to go about RE after reaching FI.
