Capitalism is not cultural
Right you are, but integrity is. Therefore your example shoots into void.
Capitalism is only an economic system. In the West it works with some ethics and rules that emanate from a social culture called democracy. It is mainly paired with the division of power into three pillars. Democratic rights should therefore be an important counterweight to the inherent excesses of capitalism.
Today in the West we can see what happens when this system gets out of bounds, especially in the financial sector. There is however a slight chance that the people eventually can correct it. Integrity means to integrate and to bring together, so these rights are essential to coerce a system back into its original design.
With cultural systems in certain parts of the world capitalism is an inherent failure from the beginning, it is a tool to tighten the grip. Every comparison with the West ("you get screwed there as well") is a cynical one. Exactly because there is no counterweight. A counterweight is the worst nightmare of certain "leaders". Therefore integrity is the first victim.
Try not giving the annual promised increase, even if it is not absolutely contractual, at a legacy carrier (EK likes to be seen as that), try even not to compensate inflation, try to fiddle the blatant inflation and try to sell a second half year worse than the first (a never seen in aviation the last 20 years) and see how far you get in a democracy as to compared to this part of the world and you get the meaning of integrity.
My biggest deception here was however not even the lack of it by local culture, it was the selling of a lot of bs by westeners with a look of a Basset, knowing that they are lying when they open their mouthes. You tend to believe them as a rookie, only to discover later that they are corrupted to the bone. Integrity, my @$$.
