Has that changed?
So yes, things are better than in my day. I would say that the number of people who would not have bothered to attend Harvard in the 80's was very small indeed.
The goal is rather to be the best in research, education and in the experience of studying for the people that do attend. They achieve that goal by significantly limiting how many people are allowed to attend, especially poor students that take money away from the school.
If you really want to help poor people, ignore what the rich are doing, ignore inequality and identify who those poor people are, what problems they have and fix them. That will be far more beneficial than attacking the "elites".

Additionally this critique is laughable and if anything proves Gladwell's point. It's not about the food, it's about spending money on things that aren't relevant to education. Gladwell could have made the very same podcast and talked about expensive sports programs instead of food.
Maybe Bowdoin isn't wasting money on food and that was a bad example to make. They're still spending a lot of money and not on financial assistance. If they felt confident about what they're spending it on, they would have brought that up and mentioned that they're not spending as much on financial assistance but instead have some large education or research project going on but they're not doing that either. Bowdoin is wasting money and they clearly know it or they would have responded differently.
