Horribly I’m I actually had a similar conversation after Covid lockdown with someone about 75 who had the attitude that the older generation should be prepared to sacrifice themselves. She believed her granddaughter needed normality and she had had her life.
I was shocked but also remember not arguing whether it was right or wrong (not going to change her mind)but simply it wouldn’t work. Thousands of older and vulnerable people couldn’t just die with no impact on society or the economy. The medical staff, undertakers etc would also be sacrificed.
