Your statement is about motivations, not fairness.
It's not very fair to society as a whole if we implement policies which impede standard of living increases.
Despite others' somewhat antagonistic answers I really just wanted to explore the reasoning behind the original statement, which I think many people instinctively agree with whilst not being able to convincingly explain why (without referencing other ideas).
Effort has a clear opportunity cost which is why I think a lot of people instinctively agree that individuals should be rewarded based on the amount they contribute to the societal pot.
It may surprise people to learn that even the Soviets effectively acknowledged the validity of that second statement. According to the 1936 Constitution of the USSR:
"ARTICLE 118. Citizens of the U.S.S.R. have the right to work, that is, are guaranteed the right to employment and payment for their work in accordance With its quantity and quality."
