If that was done, then the US sailor & the law that you suggest will be laughed out.
While the 3rd world (Indian/Filipino/Chinese) wages may look low, they in fact, earn much more than their US counterparts. They get paid in US$
a) when converted into their local currencies, is a more higher income, than what an US sailor gets paid. E.g., an AB making $1200 min, on a foreign flagged ship, would be INR77238/PP60354/Rnb7934. That income is significantly higher than their countries cost of living or what their land based peers earn.
b) that income, for them, is tax free, while the US sailor (depending also upon the state he lives in) is taxed.
c) Social security in India is tax free while the Philippines taxes it at 11%.
d) Most Indians and the Filipinos that I’ve spoken to, especially the unlic., own their own homes. Wiki US home ownerships and both India and the Philippines are higher on the list than USA.
Compare a&b to the taxes that we pay in USA with more yet to come, after the current tax bill is passed, and now you see the reason why there are many deep sea US sailors living abroad in Philippines, Thailand, Vietnam etc.
It’s a common fallacy to think that the 3rd world sailors make less money than the US sailor, when after converting that income into their home country currencies and benefits, its the US sailor who is at the losing end, in terms of income earned and taxes paid, while still having to pay bills, all in US$.
P.S. - An Indian captain of a NYK car carrier, whom I met in JAX last year, when asked how much he made, was open enough to say that he made US$10000/pm aka INR 640,000/pm, TAX FREE.
There’s a reason why the sailing job boards abroad are filled with Indians and Filipinos, all clamoring for sea jobs. If they were so low paying, as we in the USA love to believe, even beggars would ride horses.
