Not to worry. If that community is anything like many "free traders" they will handle this with name calling and insults about Professor Samuelson's age.
When Samuelson was pro-free trade, before joining his "fellow liberals"...you respected him?
Don't be lying now...
Here is a man who wants a World Immigration Organization that protects migrant labor and the various developing countries' "diasporas."
The host country benefiting from the labor would be responsible for the workers' "human rights" while the workers (nonresident citizens of the source countries) would pay their taxes to the source country.
Kinda like the Mexican model where the corrupt government of Mexico demands (and is about to get?) "human rights" for its citizens and its citizens sends billions in remittances to Mexico. Some remittances (group remittances via home town associations, HTA) go to corrupt government entities to finance public programs. Taxes, IMO.
