Republics are necessary for limited governance. Given that individuals frequently don't use the voting booth for governmental tasks, democracy truly doesn't work well with a limited government.
They sell their votes to politicians who will pay the greatest price for them, and they exploit the government to get an endless supply of free things.
A democracy will start to ignore the rule of law when systematic thievery becomes the norm because it must in order to exist, no matter how severe the corruption. When the next check comes is all that matters.
