The data is very clear. See in particular in terms of how people need to be relieved:

1. Lower the value added tax, 0% for staple foods.
2. Lower social contributions.
3. Lower the income tax.

In that order. Note that lower social contributions can (and should) just be balanced via the federal budget.

But since people vote for parties that will never do this and all but ignore parties that would, people will continue to get screwed.

I agree that social hierarchies are a feature of homo sapiens, hence why any good form of governance should be based on restricting our worst instincts. That’s what the original liberalism improved with the separation of political power into executive, legislative, and judicate branches. Unfortunately, the same was not done for economic power, which - most liberal democracies - allowed to keep concentrating with few to no safeguards.
