Every time I read stuff like this I facepalm...literally. The level of ignorance in this statement, and in those of similar beliefs, is stunning.
First off when we talk about "trickle down economics" we are referencing the Reagan years. From a factual standpoint, more wealth was created between 1985 and 2005 than all other time periods in our nations history. We saw the dotcom boom emerge, mostly from lowering capital gains taxes and encouraging investment. We saw our standard of living grow exponentially.
Secondly, no economic theory or plan is done in a vacuum. You can't look at results and say it worked or didn't work all by itself. For example, many like to look at the tax rates during the Eisenhower administration and point to the economic boom we were going through and trying to establish a causal connection, while ignoring, either conveniently or ignorantly, Europe and Japan having to rebuild after WWII and the US being almost the only seller on the global market at the time.
Thirdly, we don't just wave a magic wand and say "we are now employing trickle down economics". Ever since the FDR administration we have been employing, in different degrees, Keynesian economics. We have, in varying degrees, been relying on increasing government spending and "demand-side economics" and to take one administration during these last 85 years or so and say "See, it doesn't work" is incredibly ignorant and stupid.
Fourthly, if you look at history, not just US history but world history, you would see just how dumb this statement is. History is replete with nations and empires run by monarchy with people living as subjects in feudal systems. Very little was advanced for hundreds of years. When the US was created and the US Constitution was written, a country relying on individual achievement, we saw in a very short period of time, relatively speaking, a huge growth in our standard of living, mostly due to investment....ie companies created to make and build, thus creating jobs. Hell, we went from two brothers in Kitty Hawk trying to create a flying machine to landing on the moon in 62 years. In a relatively short period of time, we went from creating what was essentially a go cart to completely doing away with the horse and buggy, and millions of jobs created to make those cars.
The main problem here is income inequality. There are literally HUNDREDS of reasons for this and to point to ONE practice and blame it all on it and come to the conclusion businesses don't create jobs is the height of stupidity. It's mind boggling this mental midget has even one supporter. I guess it's a result of ignorant people who just don't want to inform themselves and instead vote on emotions and sound bites.
