回複：回複：這算不算勞動剝削？美國有什麽樣的法律管這樣的事？

You are right about it. B can not collect money from goverment directly; however A can. However A can not collect from goverment from B's service. Otherwise A is fraud.

So A is fraud without B's agreement because A actually did not do all the service and both A and B are independent contractors.
