A theory of justice (except for dirty foreigners)

Apparently John Rawls, the most important political philosopher of the 20th century, wasn't that bothered about global inequality. He supported barriers to migration, and supported only minimal amounts of international aid. I feel so let down. It feels almost like Jeffersonian levels of hypocrisy.

"in a much later work, The Law of  Peoples, published in 1999, Rawls went further and addressed the issues of global governance and global justice. There Rawls, at times explicitly and at times implicitly, discussed global income inequality and global income distribution and rejected the application of the "difference principle" globally.
