You get a sense from conservatives that they have a utopian view of a perfect government and that somehow if they could just force that model on the population all would be 'great'. There are no perfect governments and never will be because they are not single entities they are made up of fallible corruptible human beings. And the very nature of government, the concentration of vast power and vast wealth draws the very people you don't want to have vast power and vast wealth. The greedy and the authoritarian. That doesn't mean all leaders are greedy or authoritarian it just means the payoff is what undesirable people crave. Hence you have corruption and cheating to gain that wealth and power and the best cheaters and most corrupt(ible), over time, gain those positions in government. Which fucks up the government, just as it does in corporations. Or any gathered group of humans who have no inner compass other than money or power.
Most forms of government would work but all of them are corrupted by the very flies drawn to the honey. The quotes on government are too numerous to list, thankfully they are readily available online.
“The heaviest penalty for declining to rule is to be ruled by someone inferior to yourself.” - Plato -
And of course “Many forms of Government have been tried, and will be tried in this world of sin and woe. No one pretends that democracy is perfect or all-wise. Indeed, it has been said that democracy is the worst form of Government except for all those other forms that have been tried from time to time." - Winston Churchill -
