The wealthy weren't always chosen to be in bigness. what it comes down to is people want a good leader of their country, generally that means someone who has an education and experience. These people tend to be richer because they have put time, work, and energy into their life to improve it. Also people don't have to donate to charities, it may be the good thing to do but what it comes down to is they worked hard for their money, why should they have to give it away if they don''t want to. That being said, it would be nice if they donated, it just doesn't mean they must do it.
You say you want equal wages but that can't work. If everyone is being paid the same, or even about the same, there would be no reason to get a good education and job. Some jobs are harder and need more time put into them, so if it were equal pay there would be no reason to get a good job. Everyone would just get an easy job because at the end of the day you would be making the same amount of money as everyone else. It be like paying someone at a job that takes little to none education the same amount as some one who spent years of their life learning how to succeed at there job. It would not work.
A lot of times though people may be working hard but only to get out of the hole they already dug themselves in. People who work hard a get a good education deserve a pay off, other wise you could have people not trying at all in life and have the same benefits as a hard working, educated person. If we had no class system and equal pay, no one would ever want to do their part in the community because what's the point? Everyone would make the same amount which gives no motive.
Yes, there are at least four classes; upper, lower, middle, working ect.... People can be put into a class by two ways, objective or subjective. Objective is when you use certain criteria such as occupation, education, or income. With objective, the author is decides which social class you are in. With subjective you would ask the people what class they think they are in. One of the biggest effects on where people are placed is how far they went in school. Statistics show that people who have a college degree end up making a higher yearly wage. There are social classes in america but it does not mean that people live by them.
