I think if you are living in a non-muslim country, you must not be so restrictive about what you can and can't do.
My younger brother is very much into religion (following the right path and be the best you can be) and he QUIT his job because they were concentrating on promoting Alcohol and non-halal stuff. I think it's a bad decision in this economy - because there are no jobs out there! (He did not want anything to do with promoting Alcohol with advertisements and stuff).
I don't see Allah helping him find a halal job ever since he quit.
ur brother took a good decision and u should be proud of him, he has his faith on Allah instead of man made economy :) i made this decision long time back and i m in very good financial condition now
