Quick comment on the Tabarrok piece:
My mother is in a nursing home. All the COVID cases that occurred there started with a staff member. The only way to have stopped this would have been to force all staff members to live in a military dorm, away from their own families. This could happen in China, but not in the US.
The nursing homes don’t have the money for this, and the staff members have young children who would suffer.
I suppose we could have had the national guard go on active duty and staff the nursing homes!
Quick comment on the Mulligan piece:
His comments are generally excellent, but he has a few funny numbers on ACA subsidies.
An ACA subsidy is granted when the cost of a silver policy exceeds 8.5% of family income.
His table says that a family in W VA could receive a subsidy with an income over $638,000.
That would occur if the ACA plan had a premium in excess of $54,000 a year…..do such policies really exist?
