> That's not what I said at all
Well, what did you mean by “just as smart”?? Most working class men and women are in fact fairly conscientious. The institutions you mentioned do select for higher IQ. Are you claiming that software development does not require a higher IQ than a typical non-professional job? There’s a lot of psychological research that suggests otherwise.
> act, many of my FAANG co-workers were not elites.
By any reasonable definition, anyone working as a software developer in a FAANG is an elite. Most of you are in the top 1% income-wise. Most of you share the same cultural values, and live in the same isolated environment (note: I’m generalizing - that may not apply to you personally).
> this is spoken like someone that's never worked in social services and is used to the "social niceties" that something like an Ivy-league education or a cozy tech job offers
Are you talking about me here, or the OP? If me, it’s particularly amusing. I went to a state school, never worked for a FAANG, and have actually worked in social services (for a charity, for 2 years). I have a very different view of working class work ethic than you do. Most people work hard.
By the way, have you worked in the public sector, or in social services?
> ...contentious issue...
No, it’s really not a contentious issue. The title of the article you referenced is misleading, if you read the whole article. Heckman doesn’t claim that social mobility is going up. He just believes that the data isn’t as bad as Chetty claims it is. The vast majority of research in this area shows declining social mobility. Some of it suggests the long decline in mobility may be leveling off. None I’m aware of suggest it’s rising.
Read Piketty, Chetty, and Milanovic. The data is clear. In the US, social mobility has been dropping for decades, and income/wealth inequality rising. For me personally, coming from small town USA, and in my own large extended family, I have significant anecdotal evidence to back this up.
