Many poor Europeans most definitely benefited when riches were found in foreign lands. A lot of them left Europe to seek their fortune in the colonies, and ended up becoming the upper class of those countries due to white supremacy there.
Even the US was set up for them to win with that "Give me your tired, your poor, Your huddled masses yearning to breathe free" BS.
Poor white people aren't completely stupid. Even if the white elites screw them over they still benefit in other, less obvious was due to white supremacy. So it's still a net positive for them.

RESPECT to any black person that makes it to the middle class and above. You successfully beat a bullshyt game that was rigged against you from the start.
