Sounds like a nice way to dismiss all Western poverty ever. Have running water and electricity? Clearly not poor...

Just pick anything that 90%+ of the population have: internet, electricity, gas, water, a car, heating, a telephone line, etc and then declare it your "line" for poverty.

I don't think TVs were ever really a luxury in the US, except in contrived Internet arguments about the lifestyles of 10th century kings, where they absolutely always were.
