I think there are concerned financial professionals who want to help their customers make the right investments. It was a concerned of Bank of America person of interest who showed me $8.95 e-banking fees, over and over again on my account's spreadsheet. I don't know if that's $895.00 for one year, or $8,950.00 (that case is still pending between me, Bank of America and Legal Shield. I have to take care of Lendmark first.)
But banks used to rip off depositors before FDR all the time. Then there were bank robberies; Minnesota didn't give a damn. Probably kept mortality down, etc.
So I conclude, brokers want their clients to make the best decisions for their futures. But once again, greed is a prime motivator. It's enticing when compound interest and the "rule of 72" jostle in the hands of broker/dealers, knowing their agents will eventually get paid, to withhold short-term information that could prolong retirement from 2020 to, let's say 2027 or 2037. There's a big difference.
