In my last remark I am not entirely right but you get the idea. Microsoft employs almost 100 000 individuals and most of them are US taxpayers. If you give them a big contract, it's good for the company, good for jobs in the US and it stimulates the economy in some way. Of course that money doesn't come back automatically the next day. But consider an alternative. Let's say that they get a contract with Samsung instead, the biggest korean company. Let's assume we had the means to follow the flow of money, how much of that money that goes to Korea will return to the US? One can start thinking about this for a long time. It's easier to assume that money spent on Microsoft = jobs and salaries and other things = taxes for govt.
