AOC is smarter and more savvy as I was at her age, although my educational experience is equivalent and similar. She understands public-choice economics, obvious from her questions during a hearing that pertained to the influence of lobbyists and money on political actors. That episode, as recorded on camera, was a line-drive and home-run.
On the other hand, I don't think she's entirely grasped the political reality concerning utopian change. We could have had universal health care if the market of private insurers had not been allowed to grow to what it is now. Sudden and profound change in that sector will be met by considerable resistance, and this is always the case when it comes to changing the status-quo. It is the reasoning behind an embrace of Incrementalism versus Utopian change. Utopian change involves unsustainable cost, or may proceed to the detriment of too many people in the political landscape. Or, it would simply be perceived as such.
That being said, and as a former mild, liberal Republican, the GOP has resisted change to our detriment. The last straw on the camel's back is Trump -- so morally depraved, so ignorant, so divisive that I'll be fine turning Red from a more acceptable Pink -- colors which have been applied differently and opposite their application during the Cold War. I'm using the Cold War meaning.
Like the Vietnamese journalist in "The Quiet American" says to Michael Caine's character: "If you are human, you should choose sides."
In any event, give her a few years, and she'll learn a lot more. That's more than we can say about the Traitor-in-Chief. A lot more.
