Artificially Low Interest Rates Get Apple and Microsoft to Borrow Money They Wouldn't Have

USA Today reports:

Apple is in the process of selling debt for the first time in more than two decades, following Microsoft, which sold nearly $2 billion in debt last week. These companies are looking forward to taking advantage of interest rates at or near unheard-of lows. Apple's debt is expected to be priced as soon as Tuesday.

What's better reason not to have a central bank than this?
