Just because Jared Kushner is related to Trump, and Trump is a dumb ass, it doesn't necessarily make Jared dumb. That said, many people graduate from Harvard who shouldn't have due to family connections and money. So.... yeah, in some ways Harvard is kind of a joke. It's only hard to get in, not hard to graduate from.
Also I meant to add that I agree with you regarding getting in vs graduating. That was my take away from the recent scandals. If anyone can get in via bribing their way onto a racquetball team or whatever and then graduate, it can't be that hard.
Also from watching some of their courses, they do have world class teachers and I assume TA to student ratios that are enviable so I'm sure there is a quality education there too.
Oh I actually wasn't really trying to make a reference to Trump though it's somewhat unavoidable. Kushner was actually known for being a terrible legacy admission before Trump even announced his candidacy, and Kushner's stent as Chief Innovation Officer/Chief Nepotism Advisor to the Whitehouse sure didn't make him look much smarter.
