@GF: it is not only rates, it is speed as well. In certain countries it takes too long to do i.e. a project company and once it is founded, you don't get rid of it after use easily. When doing a 6 month project with a dedicated company, in certain "developed" countries it takes 6 to 9 month in advance to do the foundation and at least 12 month further running the zombie after declaring end, so you have at least three annual accounts filing limbos and bureaucracy, for half a year of real work. Until somebody finds a way to reduce such stupid administration overhead, there is a need for the fast and easy way.
