The Europeans are doing something wrong. But it can't be down to the socialist climate bullshit, overregulation and permanent interventionism or the states' money-printing, debt-inducing policies. These are clearly success factors that should increase the productivity of the private sector.

The EU’s regulations are so entrenched I don’t see how Europe can break free.
Break german cash deoposits and the whole bs disappears

This may be a dumb question, but how do they actually measure productivity?
Nono. Good question. Normally it's output per working hour
And they measure output by taking what...the profit from the company? That seems reasonable.
A lot of times when something is measured it gets twisted. Like for instance, if output is measured in terms of how many pages of a report you write, and you find ways to pad it, to make it extra long.
I'm sure we all remember as kids who had to write a 3 page report. Hello large fonts and wide margins!
They have more developed companies compared to the USA.
That is good and bad for the market.
