The logic of this article is that high income people should not pay higher taxes. The statement " I work hard for what I got and now people are taking it away" would be true for any taxpayer. At root of this is the question: do we need taxes? If you believe in good health care, good public education, a basic income for seniors then yes we do need taxes. The tax burden should  on those with more material wealth. Those that have benefited from the system should be expected to contribute more. That isn't 'class warfare'; that is common sense.
