Retirement tax questions

@macuser_22:  Thanks for the response.  

So, regarding my question about double-taxation, if I contribute $6,000 of after-tax money to a traditional IRA, but have a separate tax-deferred IRA account valued at $600K, then the non-taxable portion of my distribution during conversion is $60, and the taxable portion would be $5,940.

Since that means most of my original contribution is being taxed during conversion, isn't that double-taxation?

If so, is there any way around this?
