To be fair, Corp Ho does make a valid point about us being too focused on PFC's tax swerves. There are indeed many other examples of companies avoiding tax that we should also be focuising on.
Here's one random example that I found on the interweb: http://host.madison.com/business/biz_beat/biz-beat-i-pay-more-federal-income-tax-than-mattel/article_82eae55e-0fca-11e1-8af8-001cc4c002e0.html
In this excellent new study, the non-partisan Citizens for Tax Justice found that many of the largest corporations paid no federal income tax from 2008 to 2010. It's not just the well-publicized case of GE
Dozens of leading companies have managed to avoid paying income taxes despite booking hefty profits. The list includes two state-based electric utilities -- Wisconsin Electric of Milwaukee and Integrys Energy, formerly Wisconsin Public Service, of Green Bay.
It also includes Mattel, parent company of Middleton-based American Girl, which counted over $1 billion in profits from 2008-2010 and still somehow managed to grab a $9 million refund from the IRS.
