No, neither of those appear in the OP and the question is somewhat different from the question in the title of the thread (the OP itself contains no questions) -- and your thesis statement does not answer the question. Though you may have thought you implied it, you didn't. For future reference, please be explicit about what your point is...however, there's still a problem:
For the points themselves:
The question in the title is actually worded as assuming they do exist (though it could imply a theoretical assumption), which is generally not a good way to word a question. The question above is much better as a problem statement.
Your Friedman quote implied to me a thesis that China is an example, answering the question affirmatively (Q: Do benevolent dictatorships exist? A: Yes, and here's an example). The Easterly quote doesn't actually attempt to answer the question or refute the affirmative answer given, but rather is a discussion of an assumed psychosis that is behind an affirmative answer. In other words, it takes as an assumption that the affirmative answer is flawed, then lists hypothetical flaws and biases that may be responsible -- without actually examining any examples or making an effort to prove the case.
The point is, if you want to answer the question "Do benevolent autocrats exist...?" you must actually examine the examples given, not talk about hypothetical flaws that may or may not apply.
