Remind me how "all these businesses" can be closed if it's really only the federal government actually takes the day off for federal holidays? Like sure some banks do as well, but most companies just stay open
Here in the real US (I.E not has make up fantasy land that he wants his user base to believe in), most companies were business as usual. As most companies only really close for Christmas and maybe Thanksgiving and Easter.
Not to mention that most Federal workers are salary, and their pay includes holidays, if he were to remove the holidays as part of the package, he would need to spend /more/ money on the workers, so it's not like it would be a plus even in his imaginary world. This is ignoring the fact that a good portion of the federal government is also unionized. so this entire plan would fall short before it even hit the water.
Yeah I wanna say the majority of people have less holidays off these days already. Hell even paid holidays (where the business doesn't close but you get 1.5x pay) seem to be shrinking.
