If an ideology is changed...

If an ideology is changed, human beings remain unchanged and there are other ways for them. Even with a human and anti-class ideology, man can carry on the exploitation of other human beings. The point is that with the changes in systems, man keeps on using his nature to play with those systems and use them as tools. Do human beings have freedom in the countries where there is followed a so-called anti-exploitation and anti-class ideology? Does there exist any equality?
