Yes things do get more complicated as assets accumulate and good advice is valuable. The question is more about where to get it. Until the 'financial advice' industry agrees to a fiduciary standard and robustly enforces it - I would not be looking there. An accountant with tax and estate experience and an estate planning lawyer would be where I would be looking. To me this is just another ad from the financial planning industry aimed at whales. The first sentence is the truest of the whole article. I would recommend Phil DeMuth's book - 'The Affluent Investor'. He starts with the same cautionary note but seems to keep it in mind throughout his book. I love the financial advisors who talk the 'Millionaire Next Door' and indexing talk but most of the time I find it just window dressing to get you in the door. The main goal is still to enrich themselves and their employer - which just to be clear is not you.
As I side note, I find it interesting how many MDs have gotten out of medicine to go into financial advising as this author has.
