Economies arent fighting and US isn’t fighting Russia. US is just supplying weapons to Ukraine.
Russia is on the offense so they have to win to get back some of what they’ve spent on their attack.
The longer the war is drawn out, the more Russia has to keep spending resources. While their economy goes deeper in debt.
Russia automatically loses if they spend more on the war than they make from taking resources from Ukraine.
Economic models keep most numbers fixed to simplify their math. They call it ceteris paribus.
So when economists claim that increasing wages will reduce the amount of jobs, they came to that conclusion by keeping corporate profits fixed while doing their math. So any business expense is paid for by reducing workers or wages.
In the real world corporate profits are not fixed and have grown faster than wages for decades.
Keep that in mind if an economist ever tries to claim increasing wages will reduce the quantity of jobs.
