Are we involved in Corruption?

I believe that a lot of people are involved in corruption, just on a smaller scale. I think that mainly adults have something to do with corruption, because adults can have power, and most definitely money, the main reasons of corruption. Money can be a huge factor on why corruption usually happens, this is because with money you can force people to pay you something for something else. This is when people have more power over that person. A example of this is when you want to get into a public school (remember, you don't pay for public schools!), but you cant get into the school, but than the school offers you to pay to get into the school, or it is the other way around. This is corruption on a smaller scale. This type of "Buying you're way into everything" process usually happens because corruption with money. Because Corruption with money is because of greed.
