How are you defining “middle class”? If it’s any worker not involved in primary or secondary industry, then changing proportions would depend on more efficient technique (a result of the technicians, or intellectuals of the bourgeois - not the entrepreneurs). Arguably, production could decline if importing were more efficient too (as long as another country has a comparative advantage in whichever aspect of production).
Also, we’d need to compare a country with similar starting criteria which didn’t have a lassez-faire approach, for whichever period.
I was talking specifically about genetically modified food. There are plenty of woo-woo websites in the US on the subject, but they gain no legislative traction. In Europe however, there have been substantially more curbs on GMO. Admittedly, these 2 European websites aren’t the worst I’ve seen:
Anyway, my point was that the GMO debate has generally has a better grip on scientific reality, alarmism aside. Anybody who wants to defend (or attack) the Europeans on this point is welcome: I see now that I was hasty to ascribe cranky motives to their regulation.
Also, as the Atlantic Magazine points out the Arizona website gives misleading information about the risks of abortion. They list fatality risks in strong language, but offer no comparison to the risks of carrying a baby to term. In the US, both risks are small, but giving birth is much riskier than having an abortion, in a relative sense. This is propaganda posing as medical advice shoved down the throat of the Arizona Department of Health Services.
