There is no meaning to the borrowing process if the lender does not achieve interest from it. He may not hesitate to lend a friend a small amount in a time of crisis, but this should not be at his expense, especially if the borrower is unable to pay. When the amount is small, there is no harm even if you fail to pay it. For important amounts, it is better to obtain a mortgage in the form of a commodity or savings equal to or greater than the value of the borrowed amount, while ensuring a reasonable profit rate that takes into account the size of the borrowed amount and the period of borrowing. In this way the process can be achieved without the need for a third party guarantor.
This might be true for many lenders, but not for the US and Euro banking systems. They get paid a HUGE amount without there being any interest. Of course, they get more with compounded interest. How do they get paid? Without the interest being included, these two ways:
1. The first way is that they treat the loan paperwork that the borrower signs, as money. The get money from the borrower when they accept the loan paperwork. It is money. Then they give the borrower his green money.
2. They get paid another full loan amount over the term of the loan, as the borrower repays the loan... because he doesn't know that he already paid it with the loan paperwork.
Banks get paid at least twice on their loans.
