Well, he works for a law firm, and they pay him the salary of a lawyer, which is good.
However, he's adopted the mentality of a lawyer, always worrying about what could go wrong, which I think is bad.
However, that reflects the culture of the law firm. An accounting firm might be different.
It is an interesting field, trying to find loopholes to save money on international taxes. But much of it is moving the paper profits around the world, and seeing how far you can get away with it before the taxing govts start complaining.
I think it could be interesting. I myself am interested in offshore finance.
And it is always a tricky interplay between the non-tax nexus and the tax nexus.
I think it depends on your mentality. If you see it as a cerebral challenge it is ok, but if you see it as wealthy multinational corporations shirking their tax obligations in the countries they do business in (which is how most lay people see it), you probably won't like it.
