Was the government less involved?
My general sense was that the government was equally (or more) monetarily involved, in terms of total funding sums.
But less involved with regulating.
Then, inevitably, fraud and scandal happened, which begat additional regulation, which begat regulatory capture by industry.
And then the government stopped directly buying/doing most things, which introduced a new layer of intermediaries, which in turn required additional regulation to police.
The older I get, the more I think paying the graft tax for direct government production but getting a simpler, more manageable/agile system might be a preferable outcome.
But I just went through Springfield Armory last week... which managed to supply 1/2 a Civil War, most of 2 World Wars, and innumerable minor wars from a government enterprise (while innovating). So maybe government successes are readily at hand in my mind.
