You let highly educated Indians in. So you think they are in tech industry, they are bosses etc. You let in South Americans jump the wall. Educated people don't jump the wall. So your perceptions(biases) of Indian bosses and Latinos is formed. On the contrary, there are as many uneducated Indians and professionally qualified Latinos who did not migrate to the USA.
Some of you may say street smartness could outsmart education. But you need some education even to realize that. World over, modern education is going astray. Standards are deliberately being set low to let more people graduate. I am not sure if this is good or bad. But, we must accept the fact that not everybody can go through the educational hoops with the same caliber. Prosperity hoops are similar too.
One flaw in modern education is that, it is promoting greed, selfishness without any consideration for fellow humans/living beings.
