Ok I understand it's possible to use these terms as if they have meaning to some demographic somewhere, but what is the point of using them without actually referring to the necessary figures to figure out what they actually mean to the rest of us?

Also: fuck me, if americans have a 700/month car payment on average most americans you're likely to interact with on a daily basis will be deep under the poverty line. Like, the actual poverty line of "struggling to survive", not the bullshit metric used to cut people off from welfare.

It’s quite common in the middle class and below in the US to spend every extra dollar you make as your income rises. This means, despite getting promotions or raises, your a savings rate remains zero (or negative).

One primary way to increase spending is a vehicle upgrade.

Most vehicles sold are used vehicles. But if you consider only the new vehicles, the average monthly payment for new vehicles is about $740/mth.
