You're right that nothing is stopping you from trying to become politically active or to emigrate, but the chances of doing either successfully are very low.

Politics favors people of certain backgrounds and/or very high charisma. The more substantial the change the higher the level of politics you need to get involved in, and the less likely you are to successfully be involved.

Emigration suffers from the problem that the less money and education you have, the more difficult it is to successfully emigrate. You can't just decide you want to move to a country, they need to decide to let you in. The bar for entry in a lot of countries is very high so it's just not an option for a lot of people.
