For a start its getting in the way of human ability to leave this earth with a unified purpose and wise use of resources and instead causes selfish use of resources to further the ends of a select group of "lucky" people which doesnt help the human race very quickly.
The gap between rich and poor is not a
cause, it is a
result.
There are two different ways to look at wealth. I won't get into details.
Most people believe wealth should be obtained depending on how much work or effort one put into earning said wealth. This idea is true in some cases, but it is far too specific. You can really branch out from this idea of wealth distribution, but I'll only use one example.
An employer hires two men at the same time. Both men share identical jobs and work identical hours. The only difference between the two men is that only one of them is a college graduate. It's not uncommon to find people who believe the college graduate should make more money, even if he is no more proficient than the high school graduate. The idea is that the college graduate put more time, effort, and money into their education. They worked harder to get to where they are (even if it's a job anyone can learn), therefore they deserve more pay.
There are a number of different views as to how effort or hard work should be rewarded, many of which conflict with one another. Personally, I believe an employer should pay the most productive person more money, not the person who went to college, but it's really up to the employer.
People become wealthy for a number of different reasons. Some of them are honest means of obtaining wealth, some are dishonest, and some are debatable. Wealth should not be obtained through theft, fraud, or any form of coercion. Wealth should only be obtained through non-coercive means. Wealth should not measure the means in which it is obtained. We can not look at wealth and simply assume that it measures how hard they worked. There are so many different ways wealth can be obtained, all of them requiring different levels of effort to obtain.
If we look at the previous example I provided, the man who graduated college made more than the high school graduate, despite having the same job. Ideally, the man who makes more money should be the man who produced more. If the high school graduate produces more than the college graduate, ideally, he should be rewarded more because he produces more. Sure, this also ties in with who works harder, but it's not the effort that's being rewarded, it's the outcome of said effort that's being rewarded.
There are many entertainers who become wealthy, despite the fact that they don't have to put as much effort into their jobs as those who perform manual labor. However, these people provide entertainment that other people enjoy and are willing to pay for. Many people would see this as unfair.
Lastly, there's inheritance. I have a huge problem with people who want to tax inheritance, or take it away completely. I don't really need to explain why people feel inheritance is wrong.
-One issue I have with people who want to tax inheritance or to take it away completely is that it punishes people for dying. Inheritance is identical to any other gift, except that the person giving the gift is dead. Let's look at Bimmy and Jimmy. Both of their parents are incredibly wealthy. When Bimmy turns 21, his father decides to give him 2 million dollars. When Jimmy turns 21, his father passes away, leaving him with 2 million dollars worth of inheritance. If we were to take inheritance away from people, then we would be punishing Jimmy for having a dead father.
-Another example is if we look at the time in which a person dies. Again, we'll use Jimmy and Bimmy. Jimmy's father spends millions of dollars on Jimmy's education. His father also buys him his first house and a small business. Jimmy inherited his wealth and has it easy. Bimmy's father had plans to do the same as Jimmy's father, except he dies when Bimmy is only 5 years old. The inheritance is taken away so that people can not inherit their wealth "unfairly". Bimmy has to go to a free public school, work for money so that he can go to college, then save up money for half his life just to open up a business. When you compare Bimmy to the middle class or poor man, it seems fair that he has to work as hard as them to obtain more. However, when you look at the picture as a whole, there is no denying that Bimmy is being punished for the death of his father.
In the end, when a person inherits their wealth, they'll use that wealth in a number of different ways. If they are irresponsible with their wealth, then they lose it. If they use that wealth to profit, then they provide goods and services for others,despite their lack of effort to obtain their initial amount of wealth.
There are a lot of people here saying that the rich work hard and that the poor don't work very hard. Though this is often true, it's not always the case. There are many different ways in which people become rich, as well as many different ways in which people become poor.
The gap between rich and poor is NOT a way in which we can measure poverty. It is NOT a way in which we can measure the well being of the people. To use it as such is asinine. If we look at many 3rd world countries where a few people own most of the wealth, we'll see that living conditions for the least wealthy, the poor, are absolutely horrible. If we look at the wealth gap in America, we'll notice that the living conditions for the least wealthy are very high, and that the number of people living in poverty is very low.
On the same note, we can not measure living conditions solely based on how small the gap is either.
