Feeling Like You Can't Get Ahead?

Yes, but that presumes a false idea: That the bottom 90% is rational.  Or even has a clue.

Income inequality is high in the US, but the support of social welfare programmes is low. In Europe, income inequality is low and the welfare states are generous. This column argues that this paradox is largely due to perceived inequality. Many Europeans believe that there is high inequality in their countries, justifying the need for redistributive policies. Americans, however, are less concerned with income differences and with respective redistributive state intervention.

Americans may just accept certain inequalities because they see them as a reward for effort and believe in the chance of upward mobility (‘American exceptionalism’).

[...]

However, as the current research on mobility reveals, countries with higher inequality are also associated with less income mobility (e.g. Corak 2012).

[...]

US citizens substantially underestimate the extent of inequality in their country. Although income distribution is significantly worse, Americans are more likely to believe that they live in a middle-class society than are many Europeans.

Why are Americans more likely to perceive their society as a middle-class model than are many Europeans?

Possibly because we are ignorant. Possibly because we have been drowning in media and political rhetoric for decades that tells us we are number one, great, exceptional people – except for those lazy bums on welfare who won’t work and don’t deserve anything anyway.

And they've worked for a very long time now.  I don't see any reason they won't keep working.
