While such action can make a difference, such as whether to put kids in cages or not, it can't really do much. You can't use it to change quotas, set a minimum wage, or allow H1B holders to change job. So calling it an "overhaul" is perhaps a bit much. It's more like a tweak that mitigates some of the abuse and issues with the system.
