” so that if they ever need to they can get a job “
In today’s economy, unfortunately, that doesn’t always guarantee employment. personally, I would never allow a child of mine to get married unless he had a job already, or she was marrying someone who had a job. The nebulous future “if they ever need a job” might shock them to discover that there IS NO JOB out there. So IMO, they should be ensuring that they can take care of their business, before adding another person’s life into that equation, by making certain they are already employed.
I also believe that being able to learn at will is a wonderful thing. But we are not living in a society that leaves that as a practical option for most of us. Parnassah has to come from somewhere. I know, I know, it’s from Hashem, but you know what, Hashem is the one who said, “B’zyas apecha tochal lechem” and He did not say “b’zayas apei avichem tochlu lechem,” for the future generations. Clearly His intention was for us to earn our keep AND learn and follow the Torah. If we did not earn a living, we would be unable to keep MANY of the 613 Mitzvos, as so many of them relate to farming, raising sheep and cattle, giving tzedaka (from what money, if we are not earning any?), and so forth. So many halachos relate to business practices, that it simply cannot be that Hashem does not expect us to put these laws to use in some way. And if we are not prepared to earn any living, there is no absolute certainty that we are in dire need of such, that we will find a job falling from thin air, just because that’s what we need.
