The bigger the government gets, the more intrusive it becomes and the harder it is to convince a majority of the people that they can use the government to live better at someone else's expense: at some point too many people become the "someone else" who is providing the financing. Therefore, as the government becomes bigger, it has to become less democratic, less responsive to the will of the people. We are seeing this now in the rebellion in the House of Representatives, the most democratic part of government.
