Confusing my ratios doesn't change the point. Restated
The Gini co-efficient equates the top 50% to the bottom 50%. Tax cuts for small business would, not unexpectedly, have a greater impact upon the income of the top 50% than the bottom 50% who are more likely to be on benefits, pension, etc.
Why do you ignore transfers and only focus on tax? Apparently, you believe we can cut welfare/social services, flat-line real wages and destroy job security with no detrimental effects. Maybe people are just imagining that their households are more cash-strapped?
Why do you begrudge all our citizens a fair share of the nation's spoils? Aren't they also worthy of a life lived with inclusion and dignity?
