Full of fail.
A) OP premise is wrong. If OP paid no taxes he would not have his ass thrown in prison so long as he owed no taxes. It's quite easy for a company to owe no taxes, regardless of "profit".
B) GAAP profit is not the same as Federal Taxable income.
C) The tax law is what it is. Don't blame the companies for following the law, blame Congress for kowtowing and changing the law.
D) According to the article, PG&E paid no income tax. Yet I can look at their annual statement for 2010 and see that they've paid $1.5 billion in income taxes in 2008, 2009, and 2010. The 2010 effective tax rate was 33.9%.
E) According to the article, GE paid no income tax. Yet I can look at their annual statement for 2010 and see that they've paid $1 billion in income taxes in 2008, 2009, and 2010.
And so on.
