Many staunch conservative are proponents of the just-world hypothesis, claiming that the rich are rich and the poor are poor because that’s the way the Universe wants it, or some such nonsense.
Two US presidents that were members of the Democratic Party, John F. Kennedy and Jimmy Carter, went on record stating that life is unfair, with the implication that people shouldn’t look to the government to solve their problems.
In Carter’s case it was referring to the fact that some women weren’t able to afford abortions even after Roe v. Wade, and was very likely colored by his own evangelical views towards abortion.
In Kennedy’s case it was referring to the fortunes of war and the everyday administrative workings of the military.
I still think that fairness is worth striving for in many circumstances however.
