President Donald Trump is reportedly considering another powerful tool for America’s pro-growth agenda: indexing capital gains taxes for inflation. The proposal, long championed by Larry Kudlow, deserves serious consideration. It would be the equivalent of adding another log to America’s economic-growth fire.

The One Big Beautiful Bill strengthened incentives for businesses to invest, innovate, expand, and hire. Capital-gains indexing would build upon that foundation by encouraging proceeds from successful investments to move into their next productive use.
