Take a step back.
A family of 4 with $22,500 in income is well below the poverty line in the US, which is ~$33,000/year.
But do you think a family of 2 adults and 2 children with a "feels like" income of $50,000 is still not scraping by in the US? That's basic survival at best.
As someone who lived much of their life in real poverty, you can live a pretty decent life on $50k in most of the US. Yeah, you won’t be posting your vacations on Instagram but who cares. Many people live a decent life within these income constraints. There is an enormous amount of government subsidies if you are this poor.
Don’t exaggerate what is required for a decent quality of life in America. It doesn’t benefit anyone.
As someone who grew up below the poverty line for much of my life — 2x the poverty line seemed like wealth to me. There are absolutely people getting by on “feels like” 50k a year.
There are not really frills, but in terms of “have shelter and food” it can work. Not everywhere is SF.
