[Boldin] Develop a feature for tax strategy optimization

Let me ask a logical question on taxes with FIRE. I am trying my hardest to retire early'ish (20 years away, but targeting 5-7 years to retire early). I have the standard 401k (pre-tax) and ROTH (post tax) and self directed brokerage accounts (post tax). I have been shifting my investment strategy a bit away from 401k and into ROTH or just simply into my brokerage account. I'm wondering if my logic is wrong? My logic is this: I pay XX% on my income today, in the future, those taxes will undoubtedly increase because the balance sheet of how the USA is spending more money than they're bringing in just isn't sustainable. I foresee a tax rate increase across all income levels and thus i've been choosing the pay today's tax rates to invest into ROTH and brokerage to avoid paying the tax rates in 10 years when I want to retire (10 years early). Yes, I know i'm missing some tax optimizations by not maximizing the 401k investments, but I'm hedging the uncertainty of future today. FWIW: I put maybe 5% into 401k to get my match, another 5% into ROTH and throw another $1500/month into my brokerage.
