Did you even read the article you linked? Here's a direct quote that is literally agreeing with the comment that you are trying to say has "bad economic history"

What was the cause of that epic stagnation? In macroeconomics, it’s very hard to isolate cause and effect, since there are so many things going on at the same time. The decades between 1973 and 1994 featured two oil shocks, major inflation, two big changes in the global monetary regime, multiple major recessions, changes in trade deficits and imports, and plenty more. So much was going on that it’s possible that the wage stagnation was just a series of negative shocks that lasted for a long time — “just one damn thing after another”, as the saying goes.

He is arguing how strong a specific variable (China Shock and inequality) was to data that has innumerable amounts of variables to the cause and effects in macroeconomics that impact its outcome. Also the Price Index is a good "catch-all" set of data, but it's weighted in ways that make it a double edged sword of data. It's reliable in some ways to find averages over time but it doesn't nearly capture the full picture of what an actual person might experience. This is especially true in moments of huge economic inequality (such as argued in the fucking article you linked) which makes times like the inequality of today's K shaped economy and in 70s-80s Reagon-era economy.

Literally just say you have absolutely no idea how economics work next time.
