I read it to the end and there is nothing new, from the very beginning to the end everything revolves around the fact that the banks didn't want to lend money to someone who showed up at their door and said "I have a great idea, give me money!". Whatever idea/business it's in case, banks have their own conditions under which they grant loans, and it is ridiculous to just go to the bank and ask for money without any business plan, or with a business plan that does not have any guarantees/collateral.
I don't like a TLDR thread with paragraph that are not appealing to read but I will have to go with what you summarized.
However, we need to get something straight. There is difference between a bank and a venture capitalist. The banks are profit oriented individuals that are ready to give you money but you must have an equivalent collateral in case you default but a venture capitals and Angel investors can like your idea about what you have on the table and fund it for a small share or percentage from what you earn without asking for any collateral, this is what banks don't do, they are only interested in their capital + interest.
I agree that we should not be naive when it comes to banks, their main thing is making a profit. But if someone has already chosen to take out a loan (for anything), he should look at the conditions (ToS) of those loans if he doesn't want to be surprised once he starts paying it back. That's something we should all know, don't sign a document until you read everything it says, even the small letters. Especially when it comes to money and all other important life stuff.
Sometimes, the way banks works I don't really blame them, the financial system is government, the president appoint to the Central Bank governor and the Central Bank governor give orders to commercial banks in accordance with what the government will like, whatever the banks are doing today, it all goes down to what the government want them to do even though they are profitable.
The government wouldn't help out and the banks wouldn't help you either, you are caught up in deep shit of matrix.
