Earlier quoted context omitted.
Professional courtesy doesn't matter much when it's now the norm not to be curteous, and thought to be unprofitable (in all the ways benefit is measured, not just in monetary terms) if the company is curteous. There is no professionalism above the level requried to maintain an increasing rate of profit. Workers in all industries since the beginning of waged labour have learned this fact the hard way.
Strong disagree. Eroding standards of civility are no excuse for lowering the bar on how you behave. I'd urge you to set an example, honor yourself and contribute to the solution, rather than compounding the problem by sinking to the lowest common denominator.
The pursuit of protit over courteousness is bound to happen when positive courteousness has a negligible and potentially negative impact on profit.
