How 'bout if Congress didn't tax them so much and they come back here on their own. You know, the old honey and vinegar story. They are outside the US because the financial climate is better somewhere else for them, the same reason I don't live in Hawaii.
I would agree ONLY if they totally removed the illegal citizens' income tax. It only serves to enslave.
If they want to tax - tax EVERYBODY - that includes Kerry, Kennedy, Bush, etc for spending! That means a sales tax. They can't hide behind their tax shelters etc that way. No more exemptions either - they only go to those that pay the criminal lawyers, politicians, and judges.
The corporations though, merit the income tax. They are not exempt anywhere in the world except here on the USA.
If they have an exemption from a different country, then that "corporation" actually belongs to that country (communist china for example).
