The data is very clear. See in particular in terms of how people need to be relieved:
- Lower the value added tax, 0% for staple foods.
- Lower social contributions.
- 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.
