I signed up for this forum in 2012, about one month into my first job. Back then, people on this very forum were already arguing about how much higher taxes were inevitable and how Roth was the way to go.
These inevitable tax hikes were so inevitable that I've somehow managed to start, pursue, and end my career without seeing them. In fact, the opposite has happened, I have experienced a sharp tax decrease. I sure am glad I didn't listen.
Stop speculating. Take the tax laws as they are, not what you wish they were.
I had a similar thought as you Paul.
Just as statements like “we wont’ ever see returns like we have before because of XYZ” have turned out to be false decade after decade, the assumption that tax rates in the future will inevitably be higher has also turned out to be incorrect.
At some point (maybe now!) one or both of these things might change. Or maybe they won’t.
Another idea/fear that gets passed around but hasn’t been mentioned here yet is the possibility that Roth funds will be taxed in the future. A congressional law put them into place, and another one can alter those funds. FWIW I think it is unlikely, but if the US suddenly feels the need to generate more revenue those trillions of savings sitting in tax-free accounts might look pretty tempting to a populist driven lawmaker.
Or the US might do away with income tax entirely in favor of a flat-tax, sales-tax, larger corporate taxes etc.
From a mustachian-perspective, there’s not much revenue (relatively speaking) to be gained from increasing the taxes paid by the bottom third of households, which is about where you are if you spend under $40k/year. Yet there’s a lot of votes there, so there’s some political pressure not to raise taxes on those households.
