You have a good choice, you probably are using at least one of Vanguard excellent index funds.

The reason I ask, and this is true of prospectus of funds as well, is that you will see 'investor return' as critical information.  *It works well for indexing being as you have very low transaction cost and generally long term holding, not short term.

The American economic system is the envy of most of the world in our ability to raise capital for investment.   One of the ways we do this prioritize the 'return to the investor', which is where corporation go to raise money.    You lose RTI, your investors don't stick around.    (and of course investors are 'ranked' by importance as well, I have plenty of investments, but I'm not a preferred stockholder in any of them).

Cutting the corporate tax rate is fine, but not if you also cut the tax rates for those people that have will be FIRST in line for the windfall.   Exec comp is next.  Wage/benefits are last.   That's reality.
