US education system designed to feed the elites?

The US high school system ranks at the bottom (almost) in the western world. These days US high-schools are unable to produce enough quality students required for the research areas in the graduate school. To fill out this blank, students from abroad (mostly China and India) are brought in. These foreign students are almost like furnished products but free of cost ( however, Chinese/Indian education system are almost subsidized by the state, so these governments have already spent to make them graduate with a BS). These students work almost tirelessly in the graduate school to meet the deadlines set by industries without much complain (working almost 365 days, even during Christmas and Thanksgiving). For the industries (mostly owned by the US elites) this means good business.....even after the graduation they continue to do so (as they are always scared of losing their status). On the other hand, bringing international students is also a big margin profit, as you can send a higher percentage of your projects to the graduate school to be accomplished by least demanding international students (hiring full time workers will cost 5 times more approximately).You see, this situation hugely favors the US elites (the owners) who mostly buy out American politicians. I am not trying to be a cynical person, but that's what I can understand with a clear mind in my 6th year of Graduate studies as an international student (I'm going to defend my PhD soon). The US elites will keep the education system running this way as this strategy hugely favors them.
