lifting the minimum wage, which wouldn’t bring much at all in the big picture, instead of reducing the enormous amount of various taxes that has to be paid from everybody’s salary
Lifting the minimum wage directly impacts the available income of the lowest income classes, who in turn spend most of their income on consumption, increasing domestic demand and thus also helping the economy.
Also, higher minimum wage gives unions a better position to argue for higher wages for their members. That in turn can put pressure on the general non-unionized wage level through competition for qualified labor, which we are told is in such short supply ("Fachkräftemangel").
Reducing income tax on the other hand primarily benefits those who pay the highest income taxes, i.e. those with high income.
Those people can afford not to spend their entire income but will instead put some if not most of these gains into personal savings, which effectively removes the money from economic circulation and does not help the economy.
Also extremely low incomes do not even pay income tax and thus would not benefit at all.
tl,dr Higher mix wage is good for everyone (at least everyone who lives off labor) and primarily helps the poor, lower income tax is only good for some and primarily benefits those with high income.
None of the really "tax the rich".
Although I would argue that a higher general wage level can help redistribute wealth from the rich to the working class.
I'm sorry, you might not mean that literally but too many people perpetuate the myth the taxes and or social security contributions eat up all wage increases or that people get even less due to higher taxes.
That is complete nonsense. The total tax and social security contribution would have to be at 100% for that to be true.
If you want people to be able to afford more with their money, then I'd advocate for lower VAT and/or dropping the VAT for basic foods and products to 0%. That wold also help the poor more, serve as a better social redistribution measure and could contribute to more domestic demand.
If we are not talking about taxes but social security then I agree that there need to be significant reforms.
