The analogy is correct but you missed a piece. The people are not "pushed out", they are in-slaved. The analogous country is monitor by other countries which set a standard for how the
"rich people" should behave in/towards it. However, you cannot live in the same place as your slaves. Therefore, what is
the mayor of said city making as a salary? The governance should is monitored by our other governance to ensure that everyone gets a say. If the mayor/governance is making too much money,
it will bee seen as a problem. After that, corruption is the only route for the wealthy people to take to have their agenda (and we all know how that ends).
P.S. Many governing job positions in America have upwards of $180,000/year salaries and then requesting raises to it. But, they are in charge of wealthy areas, not doing a "superb job" which deserves
as huge salary.
