basically the moral of the story is that businessmen can't be trusted to act like decent human beings (what a surprise/who would have guessed)
the moral of the story for the liberals is this: a "democratically" elected government doesn't care about the wishes of those who elected it to power. the state in a bourgeois liberal democracy is a tool created by the ruling classes to serve the interests of the ruling classes. for example, the majority of americans favored a single payer healthcare system. however, we ended up getting what the insurance companies and big business wanted, more shitty industrial-medical-insurance complex. another example is american foreign policy. most americans don't like war. however, the us military/cia has intervened in many countries to secure favorable conditions for capital accumulation for giant multinational corporations
