Some working guys will make 30k their whole lives. It depends..
true, and if they build a true bayis ne'eman, have a k'viyus in learning, and raise great kinderlach who are real mentchen,
make a Kiddush Hashem in public and their line of work, live an ethical life of elevating gashmius to kedusha, inspiring others to Yiddishkeit,
(and still get free health insurance, subsidized rent and food) and have some DDF inspired supplemental income and vacations,
then they may accomplish far more than an average, random person earning $80K in an office.
