| As an engineer and computational scientist, drawing conclusions from correlations like this is absurd. Maybe Reagan was good for income inequality or maybe he was bad for it. Did you control for the other variables before drawing your conclusions? What about: * The governments' legislation and economic policies in countries like the USSR, China, etc. in the 80s * Changing technology especially communication technology * Changing levels of education in the world. * Lingering/diminishing trends/effects from wars like: Cold War, Korean War, Vietnam War, etc. * Changing age distribution of humans in western countries, And on and on. The world economy is extremely complex with heavy nonlinear feedback effects. How can you possibly state things like Reagan caused X w.r.t. the world wealth distribution with such confidence? |
Drawing absolute conclusions in this area is nearly impossible, and we can't say with any certainty that Reaganomics caused this problem. The evidence does seem to suggest that the policies are not fixing the problem, which is a far easier claim to make. They might not be the cause, but it seems very likely they aren't the solution.
