how sometimes "interesting" banks do money..

So, in A country there is interesting ways to make a profit from money..imagine that it is also crisis...people do not have money,banks too,and government decides to help people..The government give lots of money to banks,in case banks after that will give to nation credits under a small rate of interest...And that do you think,what happends actually?? I will tell you: bank takes lots of money from government,and after that in stead of giving them to the nation,they just put that money into circulation....so money makes money..for example:bank recieved money in 10000 pounds from government,and then that 10000 p. bank put in circulation,and not long after bank made a profit from 10000 p. in size of 5000 pounds,so bank now has 15000 pounds. and only after that they will give these 10000 p. to nation as a credits...so finally bank made 5000 pounds from "nothing"...that's easy,isn't it???))))
another way to make easy money: for instance,russian bank takes a credit in 50000 pounds from foreign bank in Switzerland, with interest rate 5% in a year. and that 50000 p. russian bank gives as a credit to a big company with interest rate of 20 % in a year...so that company after some time have to give money back to bank in size of 60000 pounds. so it is time to bank to give back 50000+50000*0.05=52500 pounds to Switzerland bank, so from 60000 pounds they give 52500 pounds back,and russian bank has a profit of 60000-52500=7500 pounds....it is quite good,to have 7500 pounds for doing practically nothing...and again they made easy money...
