The legal system is corrupt and all about money? The police that arrested me got mad when I got off.?

I was originally charged with impaired driving, failing to remain at the scene of an accident. I side swiped a empty parked bus with the back of my truck in December with icy conditions. Honestly, I was unaware that my truck and the bus came in contact with each other because no damage was ever found on either vehicle and the bus company didn't file a damage report. The bus driver saw me and grabbed my license plate and called the police, so when I pull up into my drive way there is a police car waiting for me. They tell me to get back here now. They put my under arrest for suspicion of drunk driving. They also mistakenly search my truck for 15 minutes without my permission. We get to the police station and they sit me in this room and tell me to call a lawyer and I freaked out on this police officer when no lawyer could be reached at 3 in the morning. So foolishly I demanded a breathalyzer test. (ALWAYS REFUSE ONE IF YOUR IN THIS SITUATION, LESS EVIDENCE THE BETTER.) I get double the legal limit. Fast forward to court. I payed a total of $6800 for a personal lawyer in my case. They have the bus driver witness there and the police officer and my test results so surly Id be convicted and face a one year driving suspension and possibly a 2000 dollar fine, plus the criminal record which I did not want. My lawyer worked his magic on the crown prosecution and got me a plea deal from a technicality. The time difference between my first breath test and my second test was 45 minutes. I pleaded guilty to Careless driving, a measly Traffic Ticket. All other charges were withdrawn or dismissed, the cop was apparently quite mad at the situation. I got a one month suspension and a $1150 dollar fine. So in total I have gave the corrupted lawyer system $8000. The crown prosecuter is going to my lawyers partners wedding. They all know each other, defense lawyers, prosecuters, and judges. If you have the money you can get off of anything. Do you think the justice system is corrupt and mostly just about money?
