2. Nixon used Keynesian economics and even more drastic economic measures.
Nixon presided the creation of CETA and various programs (YOC, NYC, etc.) to employ the 14-18 year old youth in economic problem areas, all were direct federal employees working on infrastructure and developing skills in those with less direct access.
There has not been direct Federal hire legislation since Reagan. In the 21st Century high priced contractors on steroids are contracted National Defense and Security with no apparent true accountability of who and how the intelligence will actually transferred to the Feds or otherwise stored or used. The system of Mercenary Contractors replaced lower cost direct Fed employees that had ultimate control over data gathered, legally or pushing the envelope.
Not to use Keynesian economics in direct federal hire for domestic infrastructure is insane or by nefarious design.
