Labor and Capital in 21st century America

Bill Gross of PIMCO writes:

During this country’s recent economic “recovery,” real corporate profits increased by four times the amount of working wages in dollar terms, and, as the chart below shows, are 50% higher than at the turn of the century while wages remain relatively unchanged, something that has not occurred since this country’s nuptials were concluded over three centuries ago. Is it any wonder that preliminary battlefield skirmishes in Wisconsin and Ohio between labor and capital promise to spread across every state of this land? (Not Texas!) Is it any wonder that Republican orthodoxies favoring tax cuts for the rich and Democratic orthodoxies promoting entitlements for the poor threaten to hamstring any constructive efforts to reduce unemployment over the foreseeable future?
