It will be interesting to see if small businesses are hit harder by this law than big businesses. Who will actually be shut down?
Will newspapers that have hired illegal aliens be shut down?
Will TV and radio stations that have hired illegal aliens be shut down?
Will banks that have hired illegal aliens be shut down?
Will entire supermarket chains that have hired illegal aliens be shut down?
Will gasoline trucking companies that have hired illegal aliens be shut down?
Will power companies that have hired illegal aliens be shut down?
Will hospitals that have hired illegal aliens be shut down?
Will cell phone companies that have hired illegal aliens be shut down?
Will cable companies that have hired illegal aliens be shut down?
Will school districts that have hired illegal aliens be shut down?
Will governments that have hired illegal aliens be shut down?
If not, smaller businesses will be able to argue that they have been unfairly targeted.
If not, expect the immigrant labor to migrate to the protected industries.
