Give it time..
Income tax when passed was only on the top few percentage of wage earners as well.
Companies are moving their IT systems to the cloud, and decommissioning their on-premises legacy systems. As they do this, the demand for on-site corporate IT departments will go down while the demand for cloud provider IT and Software as a Service (SaaS) and Platform as a Service (PaaS) provider IT departments will grow.
The thing to watch is whether the displaced corporate IT department workers migrate to cloud and software vendor departments, or if they get left out due to cloud and SaaS vendors using H-1B workers instead of obviously qualified displaced American workers.
