Hi there!
I would rephrase a phrase in chapter 4, from:

This means that the wage people would have if they didn’t receive education ,$Wage_0$, is the same if they do or don’t receive the education treatment.

To either

This means that the wage people would have if they didn’t receive education $Wage_0$ is the same if they do receive the education treatment.

or

This means that the wage people would have, $Wage_0$, is the same if they do or don’t receive the education treatment.

so it's more understandable!

Thanks,
Best,
Angela

Correction, I think the phrase was written that way because $Wage_0$ is a counterfactual.

So maybe I would explicit it, as repetition with counterfactuals is never enough:

This means that the wage people would have if they didn't receive education, $Wage_0$ (the potential outcome under no treatment, a counterfactual - that we cannot observe), is the same if they do or don't receive the education treatment.
