Net worth is deceptive, because that's going to include illiquid assets such as housing. Are people supposed to take out a HELOC to pay their medical bills?
Median net worth in the US not including primary residence (an odd choice considering this is many folks' largest asset and is easily used to pay for things) is 40k.
It is silly to pretend like $1500 is not a possibility for "the majority of Americans". Certainly I do acknowledge explicitly in my post that there are millions of poor people in America.
