Hey, Proactive_piccolo and Accomplished_chameleon
10 years ago,people asked banks to lend them money when they knew they couldn't be pay it back. This then caused the banks to go out of business because they expected profit but never recieved it as the people borrowing money weren't in the financial position to pay it back. Added to the problem was the fact that the banker's bosses encouraged the bankers to take risks with other peoples money as they gained a bonus from their bosses.
The Bank of England then had to rescue the banks that were left with the money collected by tax collectors but the banks still couldn't receive enough money from the people that owed them some. The banks slowly recovered and are now almost fully recovered and they can now fully lend and restore money, keep money, save money and get profit.
