Dandarc,
Roth's have limits. My spouse and I have a combined over 123k in these accounts. You can only withdraw principle tax free, and if we both do 11k per year, that might take us 5 or 6 years to fund one year of early retirement, at our current over spending. Roth's alone won't get us to the promised land, which is why we stopped funding them and switched to a taxable account instead, which ironically, we pay 0 taxes on (I also live in a state that doesn't tax capgains and only taxes dividends over $2500 per year, which I haven't hit yet in the taxable account).
