So what should we do to fix the problems?
First step is to immediately close the borders. Then develop a skills-based immigration system, not a geographically focused immigration system. F refugees. The problems of the world are not ours. Our problem is keeping America a leader in technology and industry. Admit immigrants in numbers that will not allow for ethnic enclaves to be formed, so that they are kind of forced to leave whatever culture they came from behind.
Make english the official language and print government forms only in english. I believe the progressives in Brookline or some other fancy place touted how quickly white kids learned spanish utilizing total immersion. Let immigrants from wherever totally immerse in english. One language, one people.
Second step is to incentivize the corporate pigs to bring industrial jobs back here. If you want young kids in poor cities to turn away from gangs and crime, you haved to give them something to turn to. Tax breaks, relieve the regulatory burden, etc. Simultaneously limit benefits to the professional welfare recipient class so that lifetime on welfare becomes untenable.
Get rid of a lot of the bullshit in education and healthcare. Math is not racist. Ebonics is not english. Your pronouns are irrelevant. Schools need to teach english, math, science, technology, history and life skills (budgeting and investing). Everything else is extraneous nonsense. ADD is crap, you just have no discipline. PTSD is overdiagnosed. Fibromyalgia is fake - you're not disabled.
Expand the death penalty and make it's application relatively quick. There is an element within our society that has been hopelessly lost to the non-working, violent lifestyle. They have been conditioned to be con artists or predators and they will not change. They simply have to be written off.
Crimes against the elderly or handicapped, forcible rape, child molestation, pre-meditated murder, identity theft, disaster relief fraud, welfare fraud above a certain amount - make them all capital offences.
Thats a start.
