Of course, if you are able to shrink the field of students to those whose parents can pay $50k for tuition, you'll immediately reduce the risk of bad academic results. So take the academic outcomes with a grain of salt... However, this could absolutely give us a path to a sustainable public education future that solves some of the biggest problems facing us. Just from the segment on their website, I got a few things:

The adults in the rooms aren't teachers and aren't allowed to teach. Almost every K-12 educator I know personally is actively trying to leave the profession because of what it has become and what the job is. If more succeed in exiting, it's going to be a crisis we don't have good answers for. Having an AI tutor model and now only needing the adults in the room for managing the kids opens up options...both for good kids, and to have better options for problem kids. You absolutely could put the disruptive kids together and not have to move them to an alternative school or give them inferior instruction, but don't have to keep them holding back the kids who are there to learn and achieve. It could go a long way for making life better for these in-classroom adults.

The 2hr learning, rest of the day for other interesting skills model could prove huge for the evolving reality of life. We've definitely had the bubble burst that education in any old thing means success, you have to learn something valuable someone else will pay you for. As AI moves in and things that are more trades-related become better-paying than knowledge work, being able to learn plumbing, electrical, HVAC, culinary, welding, etc in the afternoons could be key to bringing back a high school education which can lead to immediate, gainful employment. We have a school like that in the district by us, and these kids who study trades skills at this magnet have jobs waiting right out of high school, the kind you can actually life on and build a career around.

I get a bit sick of the hyper-polarization of politics these days, particularly when someone has a very practical problem like wanting to leave the corporate world and is scared about his family's health well-being. Enough of you pulpit-pounding blowhards, on both sides.

Unlike most of these folks, I didn't really know about this myself, but are likewise interested in this for similar reasons to you - I hope to get out of the corporate world at some point in the next few years and had the same question. What I found was more encouraging than what many of these folks would have you believe. Unfortunately, I also found the the options appear quite regional, so my answer will only help you get looking at it for yourself, unless you happen to live in Texas, just like me.

The most wonderful finding I came across, for Texas, was this: http://www.txhealthpool.com/

Basically, it appears that in my state this issue was tackled by the state legislature, and they set-up a state-wide health insurance purchase pool for people who fall through the cracks in the current system (e.g. If you're eligible for company-insurance, you can't buy this). In has multiple deductible/co-insurance levels to choose from, and also has a prescription drug plan too. It's not too expensive, sounds about the same or less than what my company would pay for individual coverage for myself. If you have a local equivalent, this might be just what you're looking for...if you don't have too many dependents.

The other big findings I came across that is worthwhile were a battery of health insurance cooperatives whose existence was made possible by state legislation about 5 years back. Some examples of the types of coops this allowed for: http://www.tdi.state.tx.us/health/lhcoopdefintyps.html

In short, I think if you do some research at the state and local levels, you might find similar programs for your area which would help. I know I feel much better about the prospects, now that I know there are better options for me in the future besides simple individual health insurance and all the risks that entails.
