This is never getting solved until both sides agree it's a priority and agree on a plan of action.
When the Left is facilitating criminal illegal immigration, aiding, abetting, running federal law-violating Sanctuary Cities, calling for illegally crossing into the US no longer being a crime, calling for ICE to be eliminated, and threatening the lives of federal Law Enforcement Agents, their families, and even their pets in defense of criminal illegal foreigners....having allowed approx. 22 MILLION illegals to already enter the US and allowing approx 60,000 more per month to enter...and calling for already-burdened Middle Class Tax Payers to pay - along with additional increasing deficit dollars - for those illegals' health care, housing, education, etc....
...how the hell are you going to get the 2 sides to agree to a plan that will stop the Left's economic sabotage / destruction of the United States?
