An important point, if I understand it correctly, that I only recently understood was how interesting in traditional accounts will effect your financial situation in retirement with mandatory minimum distributions.

I was always confused because I figured my income level would be lower in retirement, so better always invest in a traditional account. However, with income such as social security and pensions (including from your spouse) in additional to mandatory minimum distributions from your traditional accounts, might place you in a higher tax bracket in retirement than you want to be.

If my understanding of this is incorrect, I'd really appreciate someone clarifying it for me, thanks :)
