What are you basing your assertion that most fortune 500 would be in the red on ? Corporate profit (post tax) are at a record high (e.g. http://elidourado.com/blog/the-short-run-is-short/).

Partly poetic license - my apologies.

The nearest I can find is http://www.uspirg.org/reports/usp/representation-without-tax... citing 18% paid on expected taxes of 35%. Which makes an extra 220 bn - almost double.

Given that the avg net margin is 6.3% (see below) doubling the effective tax rate would cause significant issues - but I need more data

Plus 1 for calling me out http://seekingalpha.com/article/428181-debunking-s-p-500-p
