We could easily have another depression on our hands if this goes on much longer. There are also many social costs - spousal abuse, child molestation, depression, suicide, substance abuse etc that are already on the rise. At least an adult victim of domestic violence might have some opportunities to escape and call for help; a child suffering at the hands of an abusive parent (or an abusive childminder, if parents have had to use unapproved childminders because daycare centers are closed) has fewer options and isn't coming into contact with mandated reporters any more.
The stupid thing is that none of this will defeat the virus. Even if we could be 100% certain that not a single person in the country is infected and reopen everything, what happens when the first international flight arrives? It makes more sense to isolate the most vulnerable (although if they are adults they should be the ones to make the final decision) and beyond that go about business as usual to the extent possible.
Since the economy is so critically dependent on consumer spending a reopening isn't necessarily enough to get things working again. How will restaurants survive if they are allowed to open but struggle to do business because most of their customers have been laid off? People who got laid off will cut their own grass rather than paying someone to do it, they will clean their own house rather than paying a cleaner, they won't eat out as often, they might go longer between haircuts, and so on. In an economy where my spending is your income that means me getting laid off hurts you as well even if you notionally still have a job.
Still, at least the fuhrer governor reminds us we're all in this together, as he retreats to his mansion on full pay. I wonder if he has sacrificed anything at all, as he talks about "shared sacrifice".
