Maybe it's a good reason to reduce public spending in general. People act like public spending is a way to even things out, but in practice as the post evidences, the more we tax and the more the government spends the more wealth has actually been concentrated.
People fall into the trap of thinking of things in broad terms like "taxes good/bad" or "regulations good/bad". There are benefits and drawbacks for each individual tax/regulation/policy/etc. What is clear is that the government tends to work for the benefit of the rich, which is a natural consequence of the influence of money in politics, and we certainly need to do something about that, but the system will be heavily resistant to such efforts.
