No. Job security in the US doesn't exist. The changes are just trying to close some loopholes and get the program back to its essence: a way to temporarily hire skilled workers for which there is a shortage in the US. It doesn't give any job security to school teachers, waiters, electricians, lawyers, etc. The entire workforce is not composed of tech people.
