And if country A prevented trade, then country B would take advantage and reap the benefits (at least short term, although the short term can be decades long).
But yes, I might have phrased my point obscurely.
As an example of what I mean. I moved into a new building here, in Czechia, twice in my life. For the first time in 2008, for the second time in 2022. On both occassions, I received the full documentation stack (in paper) for the building.
The 2022 stack is almost three times as thick as the 2008 stack. Endless reams upon reams of certificates, medaillons, permissions, test results etc. Is the 2022 building three times as ecological as the 2008 one? Not even remotely, the 2008 building was just fine in all parameters I could judge, a nice middle-class home with low energy footprint.
Somehow, the bureaucratic documentation requirements tripled in 14 years, surely not overnight; more likely, a new regulation came into force every fortnight or so, adding a page or two to the total stack. Each of those steps was probably seen as insignificant by the authorities, but their aggregate effect must be significant. People spent time and resources achieving all those certifications; at the end of the day, it was me who paid for all that work.
And for what gain precisely? The law of diminishing returns is strong in this regard. Most of the really important regulatory stuff was probably already in place by 2008. We didn't live in mud huts with outhouses and didn't burn dirty oil for heat in that building.
This is the kind of red tape running amok that leads to stagnation and high living costs in the West.
I think this has a lot to do with ever stricter environmental regulations; construction is hitting the same roadblock, environmental assessments are onerous in many places of the West. As a result, manufacturing moves to Asia and housing doesn't get built at all.
Software, which doesn't face the same hurdles, flourishes in the West. A typical consumer combo is Asian hardware with European/American software. I don't think we are out of innovative spirit just yet, we rather have to prune the regulations a bit, because well-intentioned or no, one can regulate himself to complete stagnation.
