The problem really is the progressive tax system, which directly promotes low productivity, since working more usually means lower and lower wages.

I met many engineers who would be completely willing to work more hours, but it makes very little sense as you are working the additional hours for far lower wages.

The idea of banning lower work times is new to me, but seems in line with the German government approach to invent an anti-solution to the problem with severe potential downsides (e.g. for parents).

"Far" lower wages? Progressive income tax is constant at 42% for essentially the whole salary range that is relevant for an engineer (66-278k).

As a concrete example, total tax burden at:

- 70k is ~40% (42k net)

- 100k with ~44% (56k net)

- 200k with ~46% (107k net)

I'd seriously question the judgement of any engineer that chooses e.g. the part time job that gives you 42k net over the full time job that gives you 56k net (= significant difference of possible living conditions/disposable income) _purely_ on the basis that you earn "far" less per additional Euro. (I think it would be very understandable to choose the less work hours just for having more free time to spend on other things.)

I feel like there is almost an inverse effect once you hit the limit on social contributions (~90k), where it becomes more motivating to earn more, as from that point "only" your income tax increases and health insurance etc. stays steady.

That's only part of the equation though.

If lower income means you qualify for subsidized housing, subsidized childcare, etc then that can be a big incentive.

I have two sisters with very similar lifestyles despite grossly different incomes. My low-income sister gets her housing, groceries, utilities, childcare and even phone paid for by government programs. My other sister (near median income) lives in an apartment of similar size and quality, buys similar groceries, etc but pays for all of it from her wages.

My low-income sister has no real incentive to increase her official income (although she does value informal economy "hustles" and side-gigs which directly give her disposable income).

Yes, for low income brackets (and certain constellations with partners, kids an joint filing) where you face subsidy cliffs, I can see that being an issue.

However that was not at all what OP argued with engineering salaries and progressive income tax leading to "far less" net income per additional hour worked. The issue you brought up has much more to do with hard subsidy cliffs and high cost of living eating up the disposable income for low income households.

Of course not just because of that. They look at the money they earn, the money they need to live and see that if they reduce their expenses a bit, they can easily do with less hours. The 66k really is interesting, because starting wages are below that (my first job was 55k), but with experience you can easily get into that range. If that happens your income before taxes significantly increase, but your hourly compensation after taxes not as much and so you obviously have to ask yourself whether the additional hours are worth it or whether you can make do with less.

Additionally it makes employers where you generally work less hours (e.g. VW) more attractive. But obviously this has an effect on productivity per person.

This is not the whole truth. You'll get actively punished the higher your salary is. At the 100k Euro mark you will lose all government subsidies and the worst part is that the government will stop paying for elderly care for your parents. Instead, you will be forced to. Independent of your relationships with them. 100k sounds like a lot but you'll be left with 55-60k Euro after taxis, with elderly care being above 3000 euro a month for one parent only.

Here are my sources: [1] Robert Habeck, our Minister for economic affairs say's we can not afford less work. [2] Saxony's Minister arguing for "40 hours workweeks for all" and say's that "part time is a mistake". [4] is Markus Söder, Bavaria's Minister telling his plans to force Teachers to work more [5].

This is a manifold problem. Low post-tax wages (except for some government workers), high stress due to few colleagues and tons of work, extremely late age of entry for pensions.
