People feel safer with the stablished order in the face of potential change. That’s partly why people buy the same things they bought before, return to the same restaurants, and keep the same opinions.
This has been called the system jutification bias, and it has interesting paradoxical effects. For instance; poor people don’t strongly support the political policies that would make them better off. Surveys show consistently that low-income groups are hardly more likely than high income groups to want taxes that mean they’ll get more money.
Oddly, the more disadvantaged people people are, the more they are likely to support a system that is doing them no favors.
In US, low income latinos trust more government than high income latinos. And in countries where men hold more sexist values, women are more likely to support the system.
The more unequal the society, the more people try to rationalise and inequality in society. This is the basis for extended wealth building myths, such as “poor people are poor because they don’t work hard enough, and rich just deserve to be rich”.
