The real unfortunate thing is that she's lucky in that she's attractive and willing to do this. There are a lot of teachers who are in the same financial situation but don't have that as an option.
Well I personally think the real issue here is teachers graduating with too much debt and the fact that most teachers are forced to have some kind of second job in order to pay their debt, bills, & rent \ mortgage.
America is an enormous country. Not all states, regions, and counties are the same. I make close to, but not quite, the median income for my state. And I work two jobs. One full time and another part time. That may be immaterial to you but it isn't for a lot of people.
I'm sorry to hear about your medical condition. That's a rough hand to have been delt. I'm happy for you that you're planning ahead and I hope it goes as well as it can for you. My 401k is pretty on par for my age (in terms of a multiple of my annual income based on goggle research). I've been putting as much as I can in but no where even close to the limit. What's pretty sad is most of my co-workers are only putting 5% maybe 10% away and they think that'll be enough. I try to explain but the vast majority don't care.
I don't think musk will corner the Internet market. I don't have a timeline in mind, and I could be wrong, but as established car makers start getting into the EV game with gusto I think Tesla could end up losing a lot of value and absorbed by one of the big international car manufacturers as their inhouse EV brand.
I can see your perspective but I think you have to also see that there are people out there who wouldn't agree.
