In a sincere effort not to derail, I'm taking this from the latter end of the ISFJ thread because I really want to continue this discussion with everyone, not just me and INTJMom and other people who derail at will.
It can still be done though. I set up my translation business and made a success of it before I managed to get any diplomas or anything. Of course, getting the PhD has gone a long way towards increasing the success and my income, but that only illustrates my point. I'm no better or worse a translator than I was before I got the PhD, and the PhD isn't even in languages (it's in history!), but the simple fact that I have those letters after my name means people will trust me more with their translations.
So basically I want to talk some more (or/and hear others talk) about the place of formal education as it is today, and whether the system might actually disenfranchize as many people as it helps to rise to the top.
And the possibility that qualifications don't necessarily tell you what you need to know about a person's skills.
