Wow, you must be out a long time because the JW religion is still against college/careers and also preparing for the future!
To be fair, for a while after 1975 and into the 1980s, the Society was more 'balanced' (to use a favourite expression of theirs) about savings and financial planning. Since then they've made fewer comments about it, although there was one Awake in 2011 that mentions savings, and even the possibility of what they call "legitimate debt" - a loan for a specific practical reason. I posted on another thread here a few months ago about that.
There's also this Awake article from 1998 about planning what to do with your estate at death (remove the b from borg): https://wol.jw.borg/en/wol/d/r1/lp-e/101998890
(Amazingly, leaving "valuable things" to the org is only briefly mentioned - you can tell this was written before the current GB took over in the 2000s!)
They sometimes do advocate saving, cutting unnecessary expenditure and being careful of scams and get-rich-quick schemes. All fair enough. It seems they touch on this subject much less these days, but at least they're not critical of them.
One thing they don't of course mention though, and that they are still negative about, is seeking more money to put away while of working age, by getting promotion or a better-paid job. That bit hasn't changed! And they're still against university education.
