Why are cops/authority figures usually so unsympathetic, mean, and cold?

That's why police all over the world are referred to as pigs. Our tax money pay for their wages and they treat us like ****. I have to go to court soon for a red light traffic violation. I turned right on red, when there were no cars moving, and no pedestrians around. Yes, its my bad for not making a complete stop, but the thing is, there were no cars moving, and no pedestrians around. It's less dangerous to do that than a crazy "think he's a street racer type" changing lanes on the freeway. Yet i have to waste my time going to court, and have to pay a fine soon and point on license for higher insurance cost. They have no sympathy for me, because im a college student working part time to help pay for gas, insurance, and school, i don't even have money to go to the movies or to buy anything other than necessities. I can't afford the damn ticket, yet judges, police, and government could afford the ticket, yet they would get away with the violations. I don't get how they think they are higher or more divine than the us (people of America, or state), when it is the we, who pay tax money that greatly contribute to their income. Also, if the police was a civilian in your shoes, they would want to save money by getting their car towed for free by AAA instead of having a police call their expensive towing buddies to tow their car out. I've seen it a couple of times where a towman tows a person's car and has a nice friendly chat with a police meaning they do business alot and might be friends from before. For people who are saying imagine us in their shoes, does that really justify to letting them treating the rest of the public like ****, even though they deal with the worst of society? Even though I'm living in one of the worst cities in America, it doesn't necessarily mean that everybody in my city is a drug dealer or robber. There are still doctors and laywers and other white collar people living in this city also. It's just so damn wrong.
