I believe that people have the right to a basic standard of living which should be subsidised by those who are fortunate enough to have a standard of living far higher.
I am well-off by Western standards and I assure you that luck has nothing to do with it. My solidly middle class parents worked hard to give me a good education and I have worked hard and put that education to good use. I am certainly not "fortunate". I object to your trivialization of my effort and your desire to confiscate the results of it.
I also want to point out that people living in "poverty" in Western countries are considered wealthy by the rest of the world. Do you feel that they should also subsidize the rest of the world?
