Your sarcasm is misplaced because yes, this has unironically been true for large chunks of Latin American history.

- Argentinians in particular are over 60% of Italian descent.

- The richest man in Mexico was born to Lebanese immigrants.

- The chief military leader of the Chilean war of independence was born to an Irish immigrant.

- Peru had a president who was born to Japanese immigrants.

These countries have all, at various times, had an influx of overseas immigrants whose birthright citizen children rose to high stations in society.

If you want to be genuine about investigating this issue you would obviously compare countries of equal wealth and economic power, but we all know that's not your goal. Could actually be a very interesting comparison if your reasoning weren't so motivated.
