Getting back to the prior intent of this thread...
In case it is useful for anyone, I recently learned that Northeastern Mutual prices their fees according to the scale of the managed amount (e.g. something like 1.5% for small accounts, but only 0.8% if >$2.5 mil ). This is common. They have a deal where they will consider familial accounts to be a single grouping for the sake of fees, despite being independently managed and billed etc. So for instance my dad and aunt have separate accounts, but together they are in a much lower cost tier. That incentivizes me to join them NWM bc I can also get that lower fee.
