And as I recall, the economy was positively booming under Ike.
There's a problem looking at mythical good times, & cherry picking aspects of it which one likes.
Big government fans would love to take 90+% of the wealthy set's income.
But desire is not causation....it's simplistic, & even dangerous to believe that 91% marginal
tax rates & boom times are linked without examining other related factors of the day.
- Government provided high earners with generous tax avoidance mechanisms.
The average tax rate collected from them in the 50s was approx 40%....nowhere near 91%
- The US had little overseas competition post WW2.
- The US had a massive manufacturing advantage post WW2.
- Health care was primitive & cheaper.
- People made do with less than today, eg, smaller homes, fewer cars, party line phones.
- Federal regulation was far less than today.
I recall the tail end of generous tax dodges, eg, accelerated 15 year real estate
depreciation. Such things distorted the market in counter-productive ways, eg,
encouraging risky borrowing, causing inflation.
But without those rate reducing tools, a top rate of 91% would indeed be "theft",
& would affect productivity. How hard would you work if gov took $91 of your $100?
Note also that this boom period also included the recessions of 1949, 1953, 1958 & 1960.
