But I generally don't see many Western economists singing their system's praises.
That said, I would dispute the claim that China's economic system is distinctly non-neoliberal. In fact, most of the key elements of China's economic reform were about bringing it closer to neoliberalism rather than taking it further away.
That's because the data is based on salary and wages, when the actual number used needs to be "total compensation". Total compensation also includes so-called "employer paid" benefits. It includes other costly mandates required by regulation.
The other problem is productivity increases are very uneven. Productivity for some jobs has gone way up, for others it has not changes. The latter are not going to see compensation increases if their individual productivity did not rise.
How does 2022 so far imply to you negative evidence of "here's what happens when you open economies?" I am sincerely curious.
Economists told us for decades that wages are tied to productivity, when all the data points in the exact opposite direction. Economists told us that opening up developing countries' markets would result in their development and increase in standard of living. How's that going in 2022?
