The mafia really became hugely powerful in the 1950s controlling large cities in America. The Kennedies fought them and it cost them their lives. The US is riddled with more minor criminals these days as proved by the 2.3 million in prison currently. If each prisoner costs the taxpayers about $100,000 a year plus the costs of an army of law enforcement then that's a lot of money. Way up in the trillions without a single useful return.
2,300,000 * 100,000 + law enforcement = $230,000,000,000 plus ??????????????????
Putin would probably cull 10% a year. The figures would drop substantially. It could come down to letting them go or culling the worst offenders.
Which brings me around to an old theme of mine. There are too many people on the earth, increasing every day, for true democracy to exist. I have never heard the word "culling" used, in ths respect, before but it is a very good one. The world is too full, these days, for villains to be allowed to exist, We cannort afford them.
Unfortunately, it is the thin end of the wedge. It is stated that a hospital, in Toledo, has given instructions not to give beds to 80 year olds. All denied, of course, now that it has come to light, but the problem will have to be faced, sooner or later.
