Let me put that into perspective: If Roth IRAs had been around in 1972 and you’d invested $10,000 after-tax dollars in LUV, Southwest Airlines’ stock, you’d have hit a grand slam. Not only would the money have turned into about $10 million, but when you withdrew the money some thirty years later, you’d have paid no taxes. Although way back in 1972 you would have paid taxes on your initial $10,000 investment, the $9,990,000 you earned in the Roth IRA would have been tax-free. That’s unbeatable.
