A loan broker generally works as an intermediary between the individual/entity taking out the loan and a commercial lender. An angel investor, on the other hand, is a wealthy individual who provides the capital/loan entirely on their own, and are seeking a higher return or ownership equity through their loan. So while, in theory, the person charging 10-15% could be either a loan broker or angel investor, I tend to believe it's a loan broker representing the amount that the commercial lender is asking for up front (potentially bundled with a brokerage fee that they are charging to act as intermediary).
Brokers are not professional but investors are. Brokers don’t have much industry knowledge (they say what they hear) but investors has sound knowledge of studying the market.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
