I said "somewhere in the top 50%", not 50th percentile. I was being purposefully vague so that you wouldn't do exactly what you have done and try to pick apart whatever definition of wealth was brought forward. If you like, you can pretend that I said "90th" percentile exactly is the exact demarcation of wealth. Or take 50% as the mean and it's ~$750k net worth. Or take a definition of "poll 1,000 randomly selected Americans if your example is a wealthy person and take the majority vote". Go ahead and take those down also, if that's how you'd like to spend your time.
Even the "$100k" house your example uses does not get you to the median (you don't get to casually add 20%+ to the house value just to get to the median). And you're, again, still living in a tiny house in the poorest areas with the worst amenities, the worst healthcare, the worst education, the worst economic prospects for your children, the worst obesity, the worst of the opioid epidemic, etc, effectively zero disposable income, zero college savings, zero travel, crappy old used cars, thrift shop clothing, pinching every penny just to pay down your mortgage quickly and get to the 40-45th percentile of wealth statistically. Worth it? Not for me.
It's a perfectly "fine" life, if that's what you want. It does not meet a reasonable definition of wealth in the US.
You can stop any time.
