The cuts to NASA as well as NOAA, NIH, USGS, USDA, FWS, DOE, etc. are not really saving that much money, but are destroying literally trillions of dollars of future economic value (not to mention all sorts of work whose value can't be

The biggest root problem with California governmental structure is harmful constitutional features added by public referendum, especially Proposition 13 (1978). I guess you can blame "government" for that, but it doesn't seem
