Yes, but at least you have the choice to move your savings elsewhere if you don't like the deposit interest/DIRT structure. You could pay down your mortgage (effectively earning 4-5% gross if you're on a variable rate), buy and hold shares (concentrating on ones which favour capital growth over dividends), you could invest in property, anything you like really - knowing that if the tax structure changes, you can make a new choice. But once your money is locked away in a pension, you are 100% at the mercy of whatever tax changes the government wants to make - increased levy, exit taxes, reduced or removed tax free amounts, reduced contributory pension because you were kind enough to provide for yourself...In other words, the increased taxes on deposit interest of late have effectively knocked 25% off my ultimate proceeds, this is far worse than even a 0.6% levy over the same period.
So you can't make a fully informed choice today - the current tax implications might make the pension look better today but by the time you can access your money, tax changes along the way may have made your choice a very poor one.
