World people say computers, engineering, medical and other brain related jobs are skilled or highly skilled jobs and these people are paid high salaries. Whereas farming, construction, mining and other hard physical labour jobs are unskilled jobs and does not require brains. These people are paid less salaries. This is the biggest idiot and meaningless argument I have ever heard. People involved in hard physical jobs, they eat more food because they burn more energy and they need more money for food. Also without mining there will be no computers. Without buildings there will be no place for skilled jobs. Basically brain jobs are depended on muscle jobs. So brain jobs and muscle jobs should be paid equal salaries. There should be no distinction between skilled jobs and unskilled jobs. Correct me if I am wrong?
