One bunch of advisors I would hesitate to use would those associated with many of the national banks such as Wells Fargo, Morgan Stanley, Bank of America, Chase, etc. All have been fine MILLIONS and MILLIONS in the US and internationally during the recent past for the financial and legal shenanigans of their officers, leaders, policy makers and department heads. Personally I'd also be embarrassed to work for such companies especially when one of their main products is "trust". If the top is rotten how bad is the rest of the operation??
To them, I think, scruples is something they just put on their toast to eat each morning.
