It doesn't make it harder to save. You can certainly continue saving.
What it does is change HOW we save for retirement. Shockingly, most folks don't contribute to their 401(k) via Roth. Perhaps because they don't get it. Or they aren't offered it.
You see Congress pass this, you can BET that 401(k) providers (read: Fidelity) will figure out how to contribute $2,400 to the regular 401(k) that auto-swap to Roth immediately.
Upside for Congress: A small gain in revenue.
Downside for Congress: IRA Minimum Distributions start waning - FAST - in about 10-15 years, costing them billions, if not trillions in future dollars.
The only thing stopping me from cheering this on, as an American taxpayer, is "This is Social Security. You won't ever pay taxes on that!"
