The thing is...if the vulnerable 20% of the population can't stay in quarantine... but 80% of the population is low risk...this is not societies problem anymore.. this is that 20%'s problem.
What's the upper limit on the percentage of people you're happy to throw under the bus? Are problems only problems if they affect 51% or more of the population?
You've got it wrong. The people being thrown under the bus are the people being sent into poverty because 20% of the population can't seem to stay in quarantine.
Would you put 100 million people into poverty to save 1 life of a person who wants to go to Starbucks to get a Peppermint Mocha?
