n0mesorah, thanks for going to the page! I understand Rabbi Meir responding to preceding contradiction – first a long discussion about challenges in many professions and then Rabbi saying that we, as a society, need all jobs, so you are or are not lucky to be born in a family with clean business.
So, Rabbi Meir says not to worry too much about choosing most earning profession (wall street), just do an easy and clean one and work well (software engineer), and Hashem will provide according to your zechuyot in that job.
