I posit that both are true: 1) US workers have shitty protections 2) Americans are ungrateful, lack perspective and are entitled. They don't understand when a pack of immigrants from wherever smuggle themselves in a container or coyote or what-have-you, and live for years together 10 people to an apartment to save up a little money to send home.
He's saying they don't realize what they have, they are not thankful for anything and they keep dramatizing over everything.
Certainly _implies_ that they shouldn't be, in his opinion.
Tantrums are OK when you're a kid, once you grow up you're expected to do better.
Telling a minimum wage worker who likely can't afford rent and are probably below the poverty line, they should be grateful because there's "starving children in africa" sounds patronizing, entitled, lacking empathy, and does no help anyone. It does not help the minimum wage worker or people in the other countries.
In America, the top one percent holds over $25 trillion in wealth, exceeding the wealth of the bottom 80 percent. That other people have it worse than the bottom of the 80 percent is only to distract from that bigger issue.
