Sociopaths aren’t the only problem with that philosophy. I agree with the philosophy but it assumes everyone wants good things. Many people want what others perceive to be bad, not because they are sociopaths but because they are different. A clear example of this is healthcare in the U.S. A large number of people actively vote against their best interests — some of the biggest supporters of the U.S. healthcare system are those that suffer under it most. People (including us) are idiots at least some of the time.
