Would you still view inequality as efficiency if you were the one whose work is deemed less valuable? It's strikes me as a very easy statement to make when you can afford not to live like the people depicted.
Efficiency is about producing more of what you like, while keeping as much of the stuff you like that has already been produced. Whenever it's brought up like you have done, it's always an ideological point to some extent, because "what we like" is not well-defined. If I define inequality as a "bad," and capital as "not necessarily a good," then an exchange of inequality for capital is not efficient.
