That's not entirely true. It's true that it's not as easy to work with a contractor living in Germany, as in the rest of the world, but it's doable. There are ways to set-up your contractor business which allows you to do that! It's not even that hard. For the employer there's an easy way to find out if they can work with someone which is called "Statusfeststellungsverfahren". ...and AFAIU all of the risk is on the side of the contractor, when she's doing business with an international company. It's up to the contractor to take care of everything tax/pension etc. related properly.
