the author is spot on, for example the so called scenario of legislation as is , is fundamentally flawed and deceptive. the scenario assume taxation as a proportion to gdp will remain constant, but on the other hand predicts real income growth to rise by 71% over the projection period. that is 71% beyond inflation. if this was to occur under present legislation there would be significant increase in tax, hence the deficit projections are way out and rely upon fictional tax cuts .
