Doesn’t your last statement, “But banks like LoanMax of the rod aycox fame have achieved much mainly by doing market research even in the rural areas and by identifying the prospective customers needs.” — a free market solution — completely negate the argument for nationalization of the banks?
True enough that in times past banks and other business made business decisions to exclude rural areas due the smaller market potential. However, rural areas today are serviced well by FedEx, satellite internet, and cell service. I don’t see any imbalance of economic activity due to distant location. Banking included.
I prefer capitalist solutions over government mandates any day.
