Swift and sure punishment. If you put a druggie in jail, they will sober up. But if you turn them back out, they just do it again. So, jail needs combined with drug treatment. Since they are living outdoors, just build big pens and a few tents. If an illegal, send them home. If the home country refuses to take them, then cut off their foreign aid and hire some of those smugglers to smuggle them back into that country anyway. If not offending, but on drugs force them into drug treatment. Drugs and booze are the bane of the nation. Tolerance isn't working. True communism does work. Russia does it to their drug users - they send them to Siberia and work them until dead. I don't think we want that. But it works.
It is amazing the number of entitled youth who think socialism just hasn't been done right yet. They argue Denmark and Sweden are socialist, but they fail to understand they have more social services than we do, and they do surrender more individual liberty as a result but overall, they do not screw with business because they recognize that it is capitalism that provides the funds for healthcare, subsidies, etc.
Look at the Swiss. Very low murder rate. And adult men are required to keep a military rifle in their home until 55 years old. A friend of mine broke his leg on a ski trip back in the 1970s, and they kept him in the hospital for weeks and charged him zero, but again, taxes are high and very importantly, a factor we try to ignore. The population is a uniform, well-educated, socially similar people. Even Indian nationals in Britain speak with a British accent, understand the King's Law, unlike the Middle Eastern immigrant who believes in Sharia and hates the ways of the west. The United States was never like that. We are a mix of races, religions (one reason many people fled to here in the first place), and we were founded by Spanish, French, and English elements. The SW was a mix of Spanish and Indian cultures that predated the very existence of USA. The South was full of slaves. The Irish migrated en masse to the US 180 years ago after the British starved them and we wonder why they still hate Britian? Germans too. My German ancestors fled Germany and its constant warring between the various Duchy's. My French ancestors were Huguenots whose families were butchered by Catholics opposed to their "heresy". And Netherlands tolerated them only long enough for them to get a charter from London to settle in America. My British ancestors fled the hierarchical society of England which kept them poor. The earliest city in the USA was Spanish - St. Augustine, FL. America wasn't a melting pot. It was stew made up of numerous cultures but all conforming to the new country as best they could. Italians came to the NE. Cajuns were run out of Canada.
Redlining was created by the government, FNMA no less, and as a result, we ended up with isolated pockets of blacks who could not share the wealth of a nation. As one guy put it paraphrased, "I grew up in the 1930s when we were all poor, but happy. We all had fathers and mothers in our house. Welfare caused our families to break up because they could get more money." The permissive society that the young today live in glorifies killing in every online game, TV show, movie. It acts like sex is free and pregnancy is painless. Not your problem. "Get an abortion" if you don't want to be a single mom. We are sick society through and through, top to bottom. And this nation has never been so divided as it is now since the election of Abraham Lincoln. And we know how that turned out. Today there are no social norms. There is no central religion except money to caution our excesses. Anything goes. And no one with money is ever punished - look at the Alex Baldwin case.
