Healthcare and education costs have increased hugely, housing costs moderately (moreso in the big cities). Overall inflation is somewhat offset by food and electronics getting much cheaper.
> I wonder how much similar market effects have "artificially" kept other prices high? An oligopoly or silent collusion/combination between sellers (e.g. as happened for flat TVs).
The healthcare marketplace is pretty terrible. Perverse incentives, no pricing transparency, etc is at least part of rapidly increasing costs. Oddly education has gotten much more expensive as well, including K-12, and there doesn't seem to be an obvious reason there.
> Also, I wonder if a different lifestyle is possible, leaning more heavily on those aspects that have gotten cheaper (one e.g. living remotely and working remotely or independently).
Yeah. If you can swing a remote tech job living in a low or moderate cost of living area, you can save enough to retire (in that LCOL location) in a couple years. It can really be single digit years if you can keep your saving rate above 90%.
