yes, no one would ever hire anyone if there was a 90% tax bracket, as evident by the way no one worked for 1945 - 1963, thank god in 1964 they got smart and dropped the top bracket to 77%, and then 70% from 64-80, then the whole recovery in the 80's still had a 50% rate., infact (91-92) and (25-31, lowering it in 1925, from 46% down to 25% that ended up helping 1929 so well?) were the only years we had a lower top tax rate then the current one.
Only real difference between now and the 90's was we lowered the Capital gains rate in 2000, and that helped the economy create how many jobs since then..?
The political punch lines that the Politicians keep BS'ing voters with really has NO Historical evidence to support there claims when it comes to jobs and taxes, actually in most cases the Coincidental evidence more leans towrd the exact opposite so YES the Correct term is BS; the POLITICIANS as norm LIE and just keep repeating crap that sounds good but don't deliver are their claims only works getting THEM a job.
