you're right. you don't have multiple parties, you have various flavors of west german neoliberalism teaming up to keep the slightly off-brand "heresies" out of government. at the end of the day, i feel that marx's class analysis is helpful here. you have a political class -- the bourgeoisie and bourgeoisie intelligentsia -- who pretty much all think alike due to their similar class upbringing through cadre-forming institutions. this class has a dictatorship over the country as they filter out those who are not like them from access to power, positions of power, positions of prestige, positive media coverage as well as other political and financial resources. the only way to get rid of them is not simply "voting them out", that's impossible because the output of bourgeoisie democracy is merely a confirmation of what class and cadres hold the power to shape public opinion and power in general, but to locally infiltrate and subvert and delegitimize the institutions of power and public opinion that facilitate the so-called "democratic" outcome so they have no more power over the people. it cannot simply be a ballot war, but must be a war over the institutions targeting those areas neglected by the bourgeoisie establishment.
