Austerity has repeatably been shown to kill economic growth and trigger recessions/depressions. Yet for whatever reason there is one party in congress who's entire economic policy is basically austerity measures. Repeatedly, the ax man comes in and cuts spending that generates multiples of economic activity in return. This happens all the time cut a $1 here and it costs $4 over there kinds of things. Infrastructure is frequently in this category, delay maintenance until it can't be repaired, or simply fail to invest until a road/bridge is gridlock 18 hours a day, or the train is to scary to ride. The current admin is doing this 10x because they aren't being smart about what they cut, just doing it for political points.
Is there government waste? Sure, but that requires micro tweaks, aka instead of hiring more TSA agents maybe decide they shouldn't be randomly selecting every 3rd precheck user for additional screening/etc, or maybe decide that investing in even slower scanners isn't the right choice. Plus, in TX having seen some of these contracts the city/state gives out, the idea that private industry is more efficient is laughable. In some cases they are basically contracting out for millions of dollars a year a job that could be handled by one or two actual government employees paid less than $100k a year.
