Would you be equally confused if it was phrased the other way?

"How many trade workers are even capable of going to Stanford?"

People like to talk about "grit" in white collar circles. If you want to see real "grit" go talk to the blue collar people who do shitty jobs at the expense of their personal health so their kids can have a better life.

The working class has an understanding of self sacrifice that is largely absent from more well-off groups.

Thank you.
