who should offset the missing work

I don't know about the rest of your questions, but generally there wont be much missing work. Unemployment is rising thanks to automation and AI, and a lot of work is bullshit busy-work anyway.

With a lot of upheaval and confusion in the interim, I truly believe we could cut working hours by 50% and still be basically fine.

Energy & Fuel policy

In 2025 the leader of the Örebro Party, Markus Allard, in a post on X wrote that he wished to see a complete elimination of taxes on energy & fuel.[48] Allard once again said that this was a priority for the Örebro Party in an X-post in 2026.[49] As taxes on energy and fuel make up 40 to 50% of the price in Sweden, abolishing them would lead to the prices being significantly decreased.

Again, never a path of substance to make this happen. This is how this spreads. It always sounds great in quips but no actual policy substance to get it across the line.

It depends on what kind of work it is of course. But a large portion of jobs don’t see a reduction in productivity because people don’t really work 8h efficiently. Some see productivity increases. In combination with better well being, less sick days etc. it can be done.
