What economic problems in particular? Some will point to FDR's new deal programs as the legacy of our economic problems. You can partially blame Carter for the debacle in Iran for the later political/economic troubles with Iraq. Bitcoin enthusiasts will point to Nixon taking the US off the gold standard as the root of our problems, and you just know those guys hate Woodrow Wilson for that whole Federal Reserve thing.

The only thing I objectively know about Reagan's spending is that it led to a certain series of US treasury bond issues. The proceeds were then distributed to the companies which made the arms. This led to a certain level of government funded employment and research activity. One would need information on the present value of that debt as a percentage of total debt incurred by other spending to make an accurate assessment.

Unless the argument is that it created an unhealthy dependence on government spending for employment numbers?

Apologies, but your question strays too far into current events, and is thus against the rules.

I appreciate that you may feel that you are asking a historical question about Reagan era policy as it impacts us today. However, we have already had to remove posts that consist of political soapboxing and scapegoating.

You might try asking this question at /r/asksocialscience, where our 20 year rule does not apply.
