The cartoonist is making the argument that minorities who work in lower wage jobs for rich white people are upset that Trump won. It's trying to say that minorities didn't vote for Trump, and that only white people will benefit from his presidency.
This is wrong, especially considering that many Latinos as well as women voted for Trump (blacks don't count, they hardly voted this election period at all).
So there you have it. Feeling over facts. Typical cauldron of Lib-tard goblin princes.
