President Trump's administration had no idea what a government shutdown would do until they started looking into it after shutting down the government:
Two devastating reports in the Washington Post over the weekend detail the horrifying scope of their ignorance. The administration did not realize that 38 million Americans lose their food stamps under a shutdown, nor did it know that thousands of tenants would face eviction without assistance from the Department of Housing and Urban Development.
It’s likely the administration was lulled into complacency by a previous, abbreviated shutdown that took place in early 2018. This interruption in funding lasted only a few days and had barely any effect. Perhaps the administration assumed a longer shutdown would work the same way, but, you know, more of it. The reality is that the effects of a shutdown compound over time. Government agencies can creatively stretch their budgets to mask gaps in funding, but at some point, their capacity to maintain services snaps. The relationship between the length of a shutdown and its impact is not linear. A 30-day shutdown is not ten times as damaging as a three-day shutdown. It is probably 100 times as damaging.
The impending reality of millions of Americans going hungry and homeless is just one aspect of the horrors that await us. At some point, the shutdown will impinge upon Trump’s C-suite constituency. Employees of the Transportation Security Administration have had to work without pay, but that cannot continue indefinitely. Already, employees at some airports have begun staging sick-outs. At some point, air travel will grind to a halt, and with it large segments of the economy. By next month, tax refunds will be in jeopardy.
Facing an economic cataclysm, Trump appears to have no endgame in mind.
Also, there's this matter of the air-traffic control system.
We're only two weeks short of the the half-way point in this presidential term, and the White House still hasn't figured out how to do their jobs.
