Nothing can change things except the utter collapse of the US economy and the burning of its cities, a singularity the other side of which is not visible. Any possible sollution would require a decision. The US no longer does decisions. It can neither stop the drug traffic nor legalize it. It can neither win wars nor abandon them, neither make money nor stop spending it, neither stop immigration nor assimilate the immigrants. Washington can beat its thumb with a hammer, yes, and notice that it hurts, but it can't stop beating its thumb. That would take a decision, and Washington doesn't do decisions.
