Why not in other situations though? The elites avoid taxes, Boomers have houses, banks are pumping up the asset bubble, while young people have student debt, can't buy a place to live (or even a car), have no assets and, if they're lucky and productive and high-earners, they "enjoy" 20% higher tax rate than owners of capital... Why exactly should anyone now act in a way that is detrimental to themselves, to save some other predators?

Remember that it takes an average of no more than 6 steps in your social network to get from any person in the USA to any other person in the USA.
To extrapolate, presumably he wouldn't feel any guilt if that vulnerable person died and he was a vector that got the virus to said person.
I wonder what a valid response to this logic is. Maybe: "not all people will be responsible, so it's your duty to be responsible". I guess he'd respond with, "But why should those people be free to enjoy themselves while I'm stuck at home?".
In any case, it's interesting how the sense of community has died.
If your behaviour is only responsible on the assumption that everyone else you meet is behaving responsibly, then your behaviour is irresponsible.
Does it really matter that it's "somebody else's fault"?
I, however, am not, and I'm supporting the local economy.
Young people also need groceries and medicine, and through the grocery store and pharmacy they are then one step from people who are one step from older people.
It only takes a handful of steps for your "nobody with exposure to the vulnerable" to be close to an empty set.
There's no such thing as no risk. I'm putting myself at risk of all sorts of things by leaving the house.
Your dismissal of "everything puts you at risk" is common when we're young, but it is misplaced as well. I suspect you know and understand that a lot of background risk is actively reduced by the actions we take, personally and professionally (justice system, laws, streetlights, seat belts etc.) so while you may be speaking what you feel, if you know better you may want to reconsider stating it as though it was a fact.

(The mortality rate figures given are per 100,000 population, so 1.8 / 1000 yields the percentage for that age group.)
Until you spread it to someone _with_ contact with the over-65/those at risk.
