An industry, any industry, manufactures products for sale at a profit. The financial services industry is no different.
One of the ways the financial services industry does this is to make things unnecessarily complex. That way you need a clever professional to make sense of it all.
There is a direct correlation with complexity and charges. There is also an inverse relationship between charges and investment return. By inference, complexity reduces returns.
But it doesn’t need to be this way. Simple works just fine for most people. Complicated works for the industry at the expense of most other people.
The more complicated the investment advice the less useful it is.
