user, I am not being obtuse. I just think that your line of thinking is prejudiced and incorrect. If these children are going to the top US unis to be educated, they will be receiving liberal arts degrees at bastions of liberal thought. In order to graduate, they will have to take courses in a variety of disciplines and will not obtain a good grade without doing some work - including participating in class. They will be living for some, if not all, of their time with a mixture of people and be hearing their voices on campus. Education has been proved to be a liberalising force, and being educated in these institutions, being brainwashed according to some Trumpites, would expose them to many left leaning voices. If anything, these institutions emphasise the importance of giving back to their students.
You are also prejudiced by their wealth. As if it will necessarily mean that they will be closed minded and selfish. History shows us that, ironically, some of the most radical people came from wealthy backgrounds - Lenin, Mao, Castro all came from wealthy families. Look at the scope and impact of the philanthropy of the Gates Foundations, Mark Zuckerberg, George Soros and Warren Buffet.
