JiHad-- I didn't ask you to respond at all-- but at this point you're choosing to ignore that everyone working in that environment had a hard life to varying degree, and you also never answered my question of where you got the claim that "whites watched" while blacks did all the work.

You're also choosing to ignore- despite proof that you have yet to refute (hint: calling it an unproven name like "sanitized" is not refuting it) - that white soldiers as a group did not have it better than black soldiers.  Race was absolutely a factor in why black soldiers had it bad-- but it didn't affect it so much as to mean they were the ONLY ones who had it bad, and that they had it even worse by comparison to anyone else working out there at that time.  As the sources tell us, many white soldiers and workers had to sleep outside- so did their superiors. Based on the job you had, you would have it "better" or worse than someone doing another type of job. Come back when you can refute that.
