This political involvement would likely be based on "self-interest".
The significance of self-interest at both the small scale and large scale levels of politics turns out to be clear once one looks not just at the "contributions" of a majority rules system but rather at its "yields" too. The commonness of intrigue gatherings, the brokenness of the United States impose code, the campaigning by associations for their individuals' self-interest, the reserves in the Patriot Act, the various instances of debasement in Western popular governments, and the disappointment of natives with their legislatures' failings all point to the significance of self-interest in politics.
