I’d argue that a group of new-tech employees is a specifically atypical example of the general population. They’re very likely tertiary qualified (minority), they’d all be earning more than six figures (minority), they’re likely on the lower end of the age bracket, and I doubt they’re representative with regards to gender and cultural background as that’s a known issue in tech. I’m not sure that cohort is in any way representative of the general population.

I’m not trying to take a stand here; I have no dog in this fight. I’m just trying to elucidate why making such an assumption might not be wise. As I’ve said before; it may be true, but I (and you) have no idea if that’s actually the case, so assuming it serves no real value.
