Subject: Re: Constructing a legacy portfolio
If you want to make it easy for your future heirs:

Some Berkshire, plus:

Vanguard Total World Stock ETF VT - The world stock market for 0.06%
https://investor.vanguard.com/...

Avantis All Equity Markets Value ETF AVGV - The factor tilted world stock market for 0.26%

A third in each would make for a cheap and easy to manage portfolio.
