I think it's expressing a snark against the "fuck them, I got mine" mentality, Latino versus Latino. Although it's nationality/ethnicity-specific, it's just another example of poor shaming. I've witnessed this first hand from some Cuban Americans, especially the older generations or young conservatives, who show great disdain for working class Latinos in general, and even show a huge contempt for immigrants in general; the "logic" being that they left their country under threat of death (true enough) and made their way up without "handouts". The obvious bullshit of this mentality is that it was the upper classes in Cuba who could afford to escape the Castro regime. Many of them already spoke and wrote English fluently, having had fine educations in private schools there and abroad. Miami FL was already the financial and import/export capital of the Caribbean region, so quite a few Cuban revolution refugees of the early sixties found professional level jobs right off the boat...and jet plane. As later waves of poor Cubans managed under horrendous and dangerous conditions to survive a sea trip in rickety, over-crowded vessels to land in Key West or Miami, they were often disdained as being trash or criminal escapees by the uber-conservative political fringes of the Cuban community. It's all very similar to how some white Anglo Americans have great disdain poor whites.
