Decades (conservative, moderate, or liberal)

[AggregateDemand]

Why do people think the 1950s was such a conservative time?

If you tried to propose the tax rates and labor laws from that era today, you'd be called a communist.

The marginal tax rates are meaningless, and the 1950s was the era before the Great Society. The only liberal part of the 1950s, imo, was the incestuous relationship between government and corporations, which was much more comprehensive than corporate welfare or inequitable tax loopholes.
