Hard to imagine how the government being shut down could be much worse than the government we’ve had over the past 9 months.
Its the ensuing mass unemployment of federal workers that will be the main difference, the federal gvt employs ~3mil people, or ~2% of all employee jobs in the US, and the regime is trying to find ways to stop paying/get rid of as many of them as fast as possible. Shutting down the gvt is a very expedient way to terrorize that entire workforce and convince many to leave, esp if they can keep it shut down for a long time, giving them chances to replace/eliminate those workers/jobs
