You are definitely sophisticated for somebody who earns a salary from a job, which is almost everybody.
However, if a wage-earner suddenly acquired 10s or 100s of millions of dollars they would DEFINITELY need some advice how to think about earning all your income passively from your money.
As I stated before, I’m retired and over the past ten years or so I’ve relied on my financial advisor for a number of things, from selling under-performing investments and buying funds with better earning potential, to converting my IRAs to annuities which pay me annual income. Recently it was pointed out that I had an unnecessarily high cash reserve (I’d been letting it accumulate in anticipation of house repairs which ended up not being as expensive as I’d expected) and converted some of it to CDs and a money market account which would pay off until I needed it.
