What is happening to the economy in Japan and Brazil?

[Plane]

  Like a laboratory of government and economics.

    Tax increases in Japan seem to have a negative effect.

      Public works projects in Brazil seem to be dragging the economy.

       Or perhaps not , everything has multiple factors , all in motion, and each of the different factors comes with a different time lag.

     Is it possible to learn from or learn to manipulate a system that is genuinely chaotic?

     Why juxtapose Japan and Brazil?

       They are far apart on the spectrum, they have both had success and failure and success in the past.
