The most common rebuttal of socialist society is that it is impossible to achieve because ‘you can't change human nature.’ Some people think that socialism sounds great but will never work in practice. They say it would only work in a world with perfect people. However, not only has ‘human nature’ changed many times in the past but there is no such thing as a static human nature. We are products of our environment, particularly of the wealth-producing system in which we live. People living under feudalism are motivated by feudal motives and think them natural and fixed, just as people living under capitalism are motivated by capitalist motives and mistakenly think those natural and fixed.
