It is okay to complain, but remember that we can't fix all wrongs in the world. We don't have time to wait for society to change. We will and have always found a way to survive and thrive.
My parents grew up in the Vietnam war. My mother had to do her homework in the shelters while American planes were bombing her city. My dad comes from a poor village and lost several brothers in the draft. My grandfather his brother fought against the french colonialist.
Despite all this, they don't hold a grudge against the west, and they still look up to western societies. Being a victim forever is not the way for success and happiness, and you will only hurt yourself in the long run. Practice gratitude, keep your eyes open for opportunities and keep hustling.
