-Everyone would be forced to wear a nametag displaying the person's first and last name (I svck with names, so this one's important)
-US Currency would go international, with one major change: no change (lol). Change svcks, everything that costed money would just be a dollar amount.
-The only taxes would be income taxes, set at about 50%. This would simplify the [censored]load of different taxes that the US uses.
-Gambling would be legalized everywhere, and all casinos would be run by the government. As a government run operation, winning any money at the Casino would be secretly impossible. This would give us a lot of money from gambling addicts, so they would actually be helping society.
-The punishment for any murder would be death, dealt to the killer in the same exact way as they murdered their victims. This would help to prevent extremely heinous murders that involve torture etc. Not going any further into this.
