* mRNA vaccines were brand-new (Pfizer and Moderna's covid vaccines were the first ever), and until 2019 were deemed not safe for human use, not because of the mRNA but because the lipid nanoparticle used for delivery had a toxic effect on cell walls. There was supposedly some sort of breakthrough that year that fixed it.
* The people most suspicious of the vaccines were actually looking into the science and whenever they brought up valid questions, it was just dismissed with the weakest of strawmen. For example, when they were talking about reverse transcription enzymes, the rebuttal was an overly simplistic "these vaccines don't change your DNA" without even addressing what they brought up. They later found studies showing human liver cells can convert the mRNA vaccines into free-floating DNA.
* The lies that started in early 2021 about stopping infection. None of the manufacturers claimed that, it came from media and politicians that didn't understand the press releases. For those of us paying attention to the vaccines in 2020, this was a well-known open question.
* Stopping the short-term safety trials three months early (the halfway point) when preliminary testing got an unexpectedly good result.
* The reported side-effects in those trials were completely suppressed in favor of the "safe and effective" mantra.
* Related to "effective" - The majority of reporting was on the population as a whole, rather than any sort of breakdown by demographics like age. If you were under 30 years old, even with the inflated numbers from early 2020 you were at less risk than from the yearly flu. For that age group, especially with no comorbidities, the vaccines were nearly all risk with no reward, but the push was for everyone to get them anyway.
But even is we give you a good faith benefit of the doubt, do you really need to ask why every person in the entire general public wasn't provided a personal medical scientist and an educator to break down what the medical scientist was saying? And do you really think that everyone having personal scientists and educators is being denied to individuals in order to get people to 'consoom'? Is big auto preventing everyone from having a free personal mechanic to explain all of their cars issues too? Big snack running a conspiracy to prevent everyone from having a free personal chef?
The incentives of the ruling class are vastly different from these of the general public. Covid was just one very clear illustration.
For the miller, yes (kindof), for the person who couldn't afford a mill, no. Their best hope was to sell their kid off as a 'apprentice' to the miller.
Of course the miller could only expand/improve their setup as much as their own skillset allowed, greatly reducing productivity which, spread out across the entire economy, provided a much lower standard of living.
