His answer is:
'If the system changes, then it produces a different set of results'
I could use my godlike powers to create a true democracy, a dictatorship or a theocracy. Different people would raise to the top in each case.
Pointing to the people who have risen to the top for any one of those and saying 'if you changed the system, none of those people would be there' is simply a trivial truism, it is not an argument for not changing the system.
