Acemoglu and Robinson again stress that political institutions don’t have to include
everyone or be truly egalitarian in order to create economic prosperity. Instead, they just need to be inclusive enough that their members choose a competitive market over monopolies. The wealthy men who dominated the English Parliament stood to benefit more from competition than monopolies, so they chose to create inclusive economic institutions. In turn, Acemoglu and Robinson argue, such competitive markets make political institutions more egalitarian over time. Moreover, because Parliament was theoretically
supposed to represent the people, petitions could have some effect on its decisions. Thus, the Glorious Revolution gave commoners a proverbial foot in the door of politics—they didn’t have true representation, but their concerns were at least heard, and when they banded together they had a certain amount of political power.
