There's some business-related reasons why I don't (I don't yet make enough money in salary for it to matter wrt deductions) but also because I think taxes will be very high when I retire and that my Roth will be taxed at a relatively low rate, subject to some "fees" or something.
I think the Roth will still exceed the value of a traditional IRA (plus it's only $5500/year, hardly huge as I get older and my net worth increases), but I would be willing to bet that the Roth IRA will not exist in the form it does in 20-30 years, and that existing ones will be subject to a tax/fee to make it "fair."
