(1) Austerity economics (on which the nation has embarked) is a cruel hoax
Any debate of Austerity vs Keynesian ecomomics is pointless because they both assume that it is the role of the government to create jobs. Austerity arguments are simply that the government can "create jobs" better by leaving capital in the marketplace, while Keynesian assumes that the goverment can be a good participant in the marketplace. Both of these are contrary to a view that the best government is a small government. Last I looked, "creating jobs" wasn't in the enumerated powers of the Constitution.
(2) Trickle-down economics is an old fraud
We must have a different understanding of the world "old" if we are talking about a political talking point that was established during the Reagan administration. Trick-down is simply a watering down of austerity economics so that it can be used as a talking point and then repeated enough until it becomes a platitude like "common-sense legislation".
The median wage, adjusted for inflation, is lower today than it was in 1981.
And? What about the average wage? If the average wage is going up then it means that those on the top are being rewarded for their economic output more than those on the bottom, but that doesn't mean the system is unfair. What is the economic value, adjusted for inflation, of the output of those on the bottom?
There is far less economic value (profit per person-hour) today than 1981 in jobs like manufacturing. There has been a shift in the jobs of low-wage jobs from manufacturing to service. If someone with no education and little skills was making a widget with 200% profit in 1981 and today they're stocking shelves in retail, I wouldn't be surprised if their wages have decreased, nor would I consider it unfair. Even though stocking shelves might require as much physical exertion it has less economic value and therefore less wages. (I'm not trying to degrade retail work here but using that as a specific example of my point.)
Rather than quoting low-information statistics like "median wage" are there any real studies on why there is a growing economic disparity? Or is this just another attempt to use a low-information statistic to push an agenda?
(3) Neither of these bogus economic theories would be as dangerous were it not for the explosion of big money in politics
Again, and? Last I checked we still have 1-person/1-vote. Or is this a claim that there is corruption in government (ex. lobbying, campaign contributions to "buy" laws)? Maybe there is some relation to the first point here where we've let the government grow too big, to the point where corrupting political power has too much influence?
