That’s not the real reason housing in Tokyo remains affordable. The real reason is they allow developers to build enough housing to meet demand. Places that were small hamlets filled with single family homes 30 years ago are now very densely populated and filled with midrise apartment buildings. Good luck trying to get anything like that built anywhere in America, or most of the western world.
Guy I worked with retired from the Navy as a captain and got whatever very generous pay came with that. Then used his veterans preference to get a job in my agency, did that for 20+ years, retired as a gs 14 so he gets that annuity plus his TSP savings plus social security in a few years. He’s still barely 60, so he is working as a consultant. I’m guessing he’s pulling down $200k with all the various incomes and maybe working 20 hours a week, and he’s got the Healthcare and other benefits for life. People trash talk the military and government but if you work the system right it can be worthwhile. Hell, I wish I’d joined just so I could get USAA.
