you american?
i know "middle class" there is weirdly broad

here the main markers of the "middle class" are:

1. your parents went to university - this one is becoming less relevant as the years go by and a higher percentage of people have degrees, it used to be that there would not be much competition for degree-requiring jobs, so a degree meant almost certain financial comfort, that comfort would lead to a more financially comfortable childhood for their kids
2. your parents own their own home - yes, home ownership is a good thing, but you can't ignore that under a western housing market, a house is a financial asset more than anything else, it's collateral for loans, a relatively safe investment, and a place to live in
3. you definitely own a car (unless you live in a city centre) and it is relatively new - newer car (usually) means less that needs repairing/replacing
4. you work a profession - you have a job that requires a degree, those almost always pay more than those that don't, another thing that is becoming more blurry as the middle class are increasingly becoming downwardly mobile

there are more but you get the idea
