But seriously though, it couldn't hurt, I mean facebook is stashing billions away that they earned in the US, I don't like the idea of anyone not paying what's just.
1. It could hurt, depending on the specific solution you have in mind. And anyway, even if it couldn't hurt, this doesn't seem to me to be a necessary or sufficient condition for adopting this (or any other) policy. Do you have any specific policies in mind?
2. It is the USG's above-average corporate tax rate that incentivizes corporations to send profits overseas in the first place. This benefits large corporations, because they have the resources to do as such, whereas smaller corporations do not.
3. Even with a specialized policy that specifically targets offshore profits, the after-tax corporate share of GDI (gross domestic income) is a whopping
7.1% -- there just isn't that much money to tax (and even less squirelled away offshore), contrary to many peoples' perceptions. So, I think it's fair to say that squeezing more money out of corporate entities would have a marginal effect on the nation's finances -- even if it didn't have any costs associated with it.
4. As for rich people, well, our tax system is currently more progressive than it was under Clinton (the Bush tax cuts made permanent for everyone but the rich + Pease limitations + PEP), and the wealthy are largely funding the government as is. This state of affairs seems 'just' enough for me. How about you?
I would be very surprised if the marginal utility of taking
even more money from the wealthy and sicking the IRS on corporations abroad is higher than addressing the government's spending problem.
