There are so many things wrong with this post that I don't even know where to start, but I can summarize them all with this:

No "career" is good when, at 50, you're still working an entry-level job.

Hedging your bets on marrying rich isn't a good idea for attractive young people, and an even worse idea for old folks with no careers.

There are ways to make an ESL career work, and the fact that these examples haven't fulfilled them does not reflect on the career path as much as their individual choices.
