Personal responsibility must enter the equation; otherwise, you're consigning those of us who have made good decisions about our health to pay the price for those who haven't.
Why does my life, as someone who has made 'good decisions', matter more than someone's who has made 'bad decisions'. Especially when many of those 'bad decisions', like obesity, are products of socioeconomic environmental risk factors. This seems like a very privileged perspective which probably isn't very productive in managing a diverse society in times of crisis.
So glad I made the decision to be born after 1970. At the time all my friends said I was crazy but it really paid off.
Solidarity must enter the equation because if you don't take care of those who are vulnerable, the economy will tank worse than it already has. People dying is expensive, and this many people dying is a lot more expensive than the cost of keeping things officially shut down.
