Historians would point toward a pressure toward democratization of states that occurs as the middle class gains more power.
Countries like France and Britain didn't suddenly decide on "parliamentary democracy" as a model out of nowhere; they developed a parliament first, when they were still monarchies, and then the parliament suppressed the monarch. The second estate (nobility) of these countries, which previously favored cooperation with a monarch, changed allegiances once the newly-empowered third estate (borgeoisie) gained enough economic power. Top-down power was effectively strangled by the combination of nobles + business owners collectively bargaining, refusing to e.g. build the monarch's war machine for wars they had no say in.
Western democracies looking at this historical model of democratization, expect that the best thing to do for a country's democratic freedoms is to economically enrich the country's borgeoisie, to the point that the existing dictator-empowered oligarchs see more value in supporting the borgeoisie than they do in supporting the dictator.
