Legal immigration based on merit

When Trump first proposed replacing the lottery system for immigration with the merit system, Nancy Pelosi immediately said he was opposed to brown skin people. It was not mentioned again since most merit immigrants have brown skin. Most Western Nations are suffering from low birthrates and they are not able to replace their populations. One way to solve this problem is immigration and the US is expert at this. Many jobs today and more so in the future require certain skills and merit based immigration will provide those people. It would be wise for the US to change the immigration laws to allow illegals crossing the southern border to be returned to their countries of origin and open the door to more legal immigrants based on merit.
