You nicely summarized the complete and total failure of liberalism. It fails to account for the lack of equal effort, the lack of equal talent, the lack of equal output. But it demands equal results. It's a special kind of stupid that could only come from the left.We have heard the term income inequality a lot over the past few years given that all jobs do not require the same levels of skill and experience and that all people do not have the same level of motivation and determination how would you ever make income equal?
