You very clearly did not understand what I wrote, so let's simplify this further.

There is one guy alone on an island. There are two lighthouses on the island. Each lighthouse needs an operator to function. The guy operates one of the lighthouses. How much do wages need to rise to get both lighthouses operating at the same time?

None, without people to operate ships there's no need for a light house.

If you make up ridiculous hypotheticals you get ridiculous answers.
