You can criticize anything you want, even if you partake in it. Most people don't really make a choice when it comes to their country: they were born there, speak the local language, have families and friends there. Few can ever leave to start anew somewhere else.

If people were never critical of their living conditions, we would never improve anything.

Same first thought: "Cool, OP is one of the richest 0.2% of people."
