An establishment is a group of powerful people
Power comes from ikhlaq, eman and resources.
The only way to bring a stable change is to create an establishment that has resources but also has eman and ikhlaq
Do not react to other forces. Choose your own battle. And be resourceful
Then whatever you will say will be a law to be followed.
To be resourceful, do business.
The establishment will be there. One option is to complain, be sad and fight with each other on what is left. The option is to be the establishment yourself. In Surah Anfal, Allah Subhana wa tala recommeds us to accumule power.
