Many of Trump's critics on the republican side claim that he is too harsh on the border, while many others want more drastic steps, although they are in the minority.
Drastic times require drastic measures, which is the reason I supported many of Trump's more controversial policies, like the national emergency declaration. While I do believe that the president should have his power limited to some extent, it's important to note that, with record illegal crossings on the border happening right now, something needs to be done, unless America were not to break down under the economic pressure, that the immigrants are going to cause thanks to the welfare state.
I'm not really the one that would ever predict something as drastic as economic collapse, but unless something isn't done to get immigrants out and also if possible remove the welfare programs, which would also in tern probably trigger countless millennials as well as make immigrants less likely to go to the United States, there were be a turn for the worse, both in the life of the avrage American, as well as economic downfall.
And of course, we need to do this step by step, but those steps better be fast, unless the situation in America becomes as bad as it is in western Europe, as well as the state of California.
