I don't society would make it to that point.
Our society and technology is built around an ample workforce. If you don't have enough qualified people to man the necessary and essential jobs the engines of industry stop running. We may be close to that today. Not because we don't have enough people but because so few of them a capable (or willing) of doing necessary work.
I believe that the economy and technology will collapse before we would rebel. Of course it maybe a distinction without a difference. Economic collapse often leads to revolution.
The willing part is of interest. I have met intelligent people that would not apply for good paying jobs because they required a drug test. That baffles me. Taking illicit drugs is more important to you than having a job that would drastically improve your standard of living.
Disagree. If AI pans out, that could be the increase in 'work force' needed, mentioned on this thread.
Some "intelligent people" will avoid drug testing IF they have used recently, and know they would fail.
As you said, they're intelligent.
They know that it's a cage, even if it's a gilded one, and depending on the drug, they've opted to free their mind.
Drug tests are to flag drugs they don't want you to use. Alcohol and other drugs? Fine. Carry on.
