Yeah, I guess it’s a YMMV type of thing, and healthcare is certainly growing in many areas, but you won’t want to be in the one that needs to shrink when it’s determined. I think the point is more that our parents’ world of working at the same place from graduation to retirement is long gone, and everyone should expect to have multiple jobs (and maybe careers) during their working life, either by choice or maybe not. I read that the millennials will have on average 10 jobs by the age of 40, at least some of those will likely be involuntary. And crazy stuff like 1/2 the jobs in 2030 haven’t even been created yet.
At the end of the day, your daughter should seek an education which will provide her with the utmost flexibility to do many different things, especially if she wants to try and make money with her passion b/c it may not work out as a career.
