The wealthy are always going to be better at find tax loopholes than the rest of us.  It is worth their while to hire experts.  Indeed, the wealthier they are, the more money they can spend on experts and still come out ahead in the end.

I think a simpler tax scheme with fewer loopholes would be beneficial to this country.

That being said, I don't blame the wealthy for doing everything they legally can to minimize their tax burden.  Taxes are always onerous.  I certainly do everything I legally can to minimize the taxes I pay - it just isn't worth my while to hire experts.
