Trump doesn't even want that. He talks about immigration how he does to garner votes. Like any other president, Trump wants things to remain how they've been. The reason the system allows undocumented immigrants to the extent it does is because they are a source of cheap labor for capitalists. Because their positions are the most precarious, they're willing to work for the lowest wages. All politicians serve capitalist interests, therefore no politician seriously wants to do everything in their power to restrict undocumented immigrants from coming into the country. Obviously, immigrants repress wages and their presence has an economic effect on the working-class in the country who were born here and were always citizens, so that point from the Right is simply a correct observation. They are just wrong to act like voting for any politician or party constitutes a solution. There will never be a "merit based immigration system" because the system revolves around maximizing profit and capital accumulation, not merit. It was never a "meritocracy."
Trump is not meaningfully distinct from any other past president, Democrat or Republican. The notable thing with him is he was outside politics and managed to pull the majority of the Republican voter base to his side. This was because capitalists in the national manufacturing sector who took a blow in the 70's tried a resurgence and backed him. Of course, connected to this, there's an unprecedented shift of discontent among the Republican voter base with the establishment Republican Party and the politicians that comprise it, because the voter bases are connected to the industries each party represent. (National manufacturing and big finance for Republicans, big tech and coastal elites with the various immigrant-dominated industries associated for Democrats.)
