Bier contends that this approach ignores the core issue of enabling legal immigration in the first place. Bier explained that Congress has not significantly updated America’s legal immigration system in nearly four decades. According to Bier, low-skilled American workers will also benefit from increased access to legal immigration. More legal immigrant workers would allow businesses to expand, fill needed positions, create managerial positions and expand opportunities for specialized workers. The analysis proposed that highly skilled immigrant workers would need their own set of reforms for the nation to reap the full benefits of legal immigration.
