A viral money expert recently told his audience that traditional 401(k)s beat Roth accounts every time, claiming the Roth IRA was a George W. Bush creation designed to pull forward tax revenue during an economic downturn. His verdict: “if you do an apples-to-apples comparison of the true cost, you’re going to do better in a traditional 401(k).” Act on that claim without checking the math against your own tax bracket, and you could leave real money on the table for the rest of your working life.
This debate stood out because the historical claim is wrong and the financial claim is dangerously incomplete. Brian Preston of The Money Guy Show took it apart with clarity, and his framing is what every saver should anchor to before choosing a contribution box on their 401(k) portal.
The History the Viral Take Got Wrong
Start with a simple fact: Congress created the Roth IRA through the Taxpayer Relief Act of 1997, signed into law on August 5, 1997. The law was signed by President Bill Clinton, and it predates George W. Bush taking office by more than three years. The account was named after Senator William Roth of Delaware, then chairman of the Senate Finance Committee, who championed the idea of a retirement account funded with after-tax dollars in exchange for tax-free withdrawals. What started as a modest savings vehicle with a $2,000 annual cap has become one of the most powerful tax-planning tools available to individual savers.
There is a grain of irony in the viral advisor’s Bush claim. The law that lifted income caps on Roth conversions was the Tax Increase Prevention and Reconciliation Act of 2005, which was signed into law on May 17, 2006, and eliminated the income limitation applicable to converting a traditional IRA into a Roth IRA beginning in 2010. That bill was signed by President Bush. But it expanded access to Roth accounts rather than creating them, and it was designed to raise near-term revenue, not to harm savers.
Once you strip out the bad origin story, the actual question becomes a math problem about tax brackets.
The Real Rule: Tax Arbitrage, Not Account Type
The choice between Roth and traditional comes down to one comparison: your tax rate today versus your expected tax rate when you pull the money out. Everything else is secondary.
Preston said: “If you’re in a low tax bracket environment today, and it’s likely your income is going to increase and be higher in the future, Roth 100% makes sense.” On the viral advisor’s core error: “They are not apples to apples. There absolutely is a better choice than the other depending on your unique circumstances.”
The mechanics are straightforward. A traditional 401(k) gives you a deduction at your current marginal rate and taxes every dollar you withdraw at your future marginal rate. A Roth flips that: you pay tax now at today’s rate and owe nothing on qualified withdrawals later. If your rate today is lower than your rate in retirement, Roth wins. If today’s rate is higher, traditional wins.
How This Plays Out by Life Stage
A 24-year-old in an entry-level position, sitting in one of the lower federal brackets, is almost certainly going to earn more as their career progresses. Locking in today’s low rate by paying tax now and letting decades of compounding grow tax-free is the textbook Roth case. Suze Orman has been blunt on this point for years: “a Roth retirement account is the best retirement account you are ever going to have, bar none. Give up the tax write offs today to have tax free access forever later on.”
A 52-year-old physician at peak earnings, facing a top marginal rate, who plans to retire on a portfolio drawdown that puts them in a middle bracket, runs the math in the opposite direction. The deduction available today is worth more than the deduction they would forgo in retirement. Traditional carries the day.
For high earners over 50, the choice may already be made for them. Due to a provision in SECURE 2.0, high-income earners who made more than $150,000 in wages from the prior year are required to make their catch-up contributions as Roth (after-tax) beginning on January 1, 2026. The 401(k) contribution limit for 2026 is $24,500 for employee salary deferrals. Workers 50 and older can add a catch-up contribution of up to an additional $8,000 in 2026, and workers age 60 to 63 qualify for a higher limit: for 2026, this higher catch-up contribution limit is $11,250 (instead of $8,000), for a potential total of $35,750 in annual contributions. For those workers above the $150,000 wage threshold, every dollar of that catch-up must go into the Roth bucket.
What to Do This Week
Stop treating this as an ideology and approach it as arithmetic. Three steps get you to the answer:
- Pull up your most recent pay stub and find your federal marginal tax bracket. Write it down.
- Estimate the bracket you expect to be in during retirement, based on projected portfolio withdrawals plus Social Security. If you have no idea, assume your income trajectory keeps climbing through your 50s and falls in retirement.
- If today’s bracket is lower than tomorrow’s, route new contributions to the Roth side. If today’s bracket is higher, route them to the traditional side. Revisit that call every time your income crosses into a new bracket.
The honest answer is one rule applied to your own numbers: pay the tax in whichever year the rate is lower. In 1997, the Senate passed the Roth IRA into law, allowing individuals to invest taxed income and withdraw it tax-free in retirement. That option has existed for nearly three decades. Use it when the math says to.
Editor’s note: This article was updated to add that the Taxpayer Relief Act of 1997 was signed by President Bill Clinton, that Senator William Roth served as chairman of the Senate Finance Committee at the time, and that the law lifting Roth conversion income caps was the Tax Increase Prevention and Reconciliation Act of 2005, signed by President Bush and effective in 2010. The 2026 401(k) contribution figures were also verified against current IRS guidance.
