Yeah this article just presents a recent narrative from a recent study, it doesn't mean it's right.
Fact is, the social sciences have completely opposite theories with completely opposite causal mechanisms or even opposite ideas about outcomes and conceptualisation. These studies can't even agree on the dependent variable, let alone the independent variable. And they're all championed by top ivy league scholars.
Take the article's theme for example, globalisation and job security. In public administration there's two hypotheses about the way the welfare state responds to job insecurity from globalisation. One is the efficiency hypothesis which expects the welfare state to retrench and become smaller, assuming increased competition forces a sort of race to the bottom effect in order for a state to stay competitive. The other, the compensation hypothesis, expects the welfare state to expand in order to compensate the losers of globalisation (e.g. factory workers in the US). A whole range of studies exist that show evidence for both hypotheses. They keep getting better, moving from correlation to causation, from aggregates to specifics, towards clearer conceptualisation and a semblance of a consensus. But for decades, this is a field where articles were getting published which could easily be written about in newspapers in an incendiary manner like OP's article about how 'we used to get it all wrong', and linking it to some recent populist movement, explaining how it all wasn't so crazy after all.
It's silly. Studies are valuable, but anyone who spent any time in academia, even as a student, should notice studies never translate well to journalism. It's particularly apparent reading about a field he/she is familiar with. The number of times I cared to look into the research underlying news articles and came out thinking 'this article is nonsense' is tiring.
And it's no surprise, I'm guilty of the same behavior of journalists. Either it's ignorance because I'm not a specialist in my field, or I just don't care. I've written a bunch of school assignments taking positions that were blatantly false, ignoring a whole range of literature that didn't agree while making it appear as if I was being nuanced, just to get the essay out of the way. Journalists are likely not much different.
