@GossiTheDog there’s a comparative aspect, a level of comfort but underpinning it all is the difference between income and wealth. Earning well does not mean wealth - people have mortgages, loans (student loans are especially bad for this), outgoings. Even high earners can struggle with child care costs.
Wherever you live, it’s likely that people around have similar houses, similar cars etc
But then look at actual rich people - it’s a different life.
