Do politicians extort taxpayers to provide funds to support their inflated bureaucracies or their exulted social position or power.
Politicians at all levels address the taxpayers pockets as their own never ending resource to achieve status, wealth or power. Politicians tell us they need funds to provide the services their constituents demand.
Examples of these behaviors are broadcast on nightly news.
City employees manage huge retirement packages and when the premium comes due, tells the taxes payer they need more to pay for police and fireman.
Public school administrators with fleets of high end cars in the motor pool, offices filled with assistants and 50 % of their school's employees are not teachers, ask for more funds or teachers will have to have 10 more kids in each class making any improvements in the 25% drop rate even more untenable.
On the national level, one politician was roundly defeated when he called out another politician for promising constituents "goodies" if elected. National politicians don't have funds to provide "goodies" to the nation, they have to dip into the national back pocket. Only on that level, they don't even have to con the taxpayers, they just take it.
Now it has been said that politicians do good for the people. I am sure that some are as noble as Mother Teresa. But I have seen more self interest then public interest.
