Yes, the majority dictates the terms in a democracy, and this can be a problem when a central govt makes decisions for people that are far away from them.

For eg rich EU bureaucrats deciding in Brussels what is good for a small village in the UK. Or a British King deciding what is good for rural Americans. Or Moscow deciding what is good for a small village in Lithuania.

In all 3 cases, the people revolted and fought to have the rights in local govts.

So, democracy has big problems, but a lot can be resolved by not centralizing power in a faraway govt that doesn't understand the local community.
