Much of the growth in business income since 1980 has come from pass-through businesses. Pass-throughs now earn over 60 percent of all net business income. In 2011, pass-throughs earned $1.3 trillion in business income compared to around $800 billion earned by corporations.
Corporations saw a huge collapse in their income following the financial market crash, falling from nearly $1.3 trillion in 2007 to $450 billion in 2008.
