Using tax money to produce revenue via employment is one of the few ways the government can actually produce jobs. The reason why right now there aren't more jobs is because there is already more than enough supply for our demand. If we raise our demand (via job production) we would hopefully raise our supply in turn causing more people to be hired. That being said, i have no clue how it would work out in the end as far as which would be more cost efficient in terms of the baked goods, i don't really know the actual ingredients of these things, all the things it took to get them to be edible. Maybe the 4 dollar muffins are mass produced in a factory where 2 ppl are employed, and maybe the 16 dollar muffins are hand made by a group of 20 chefs. I have no clue obviously
