I am not sure of this (or maybe I misunderstood your point, sorry). Instead of retail clients, which could get a raw deal from the bank, we can look at inter-bank rates for a sanity check. And those rates, paid to non-retail customers (who know well how to derive a maximum risk-adjusted value) are still very, very low today. US Treasuries yield curve shows pay 0.3% for a 1-year and 1.5% for a 10-year. While it is certainly harder for a company to get rates as low as US Gov't, solid businesses can get money for 2-3% and weak ones for 5-8% in as large a chunk as they want. Why would they spend a lot of effort chasing retail clients (which are a pain to deal with) and offering them way more?
