I would reduce unemployment by requiring firms to hire a certain minimum number of employees. The minimum would be determined by the company's annual revenue. I would also make it illegal to work more than 35 hours a week, and everyone would be guaranteed 30 days of vacation.
I would dismantle the entire highway system, and replace it with railroads. Or I could simply rip up the pavement, and lay the tracks on the layer underneath. Trains would run between cities every hour in populated areas, and every four hours in less-populated areas. Basically, we would have what America used to have in the late 19th to early 20th century.
In cities, streetcar tracks would be once again laid in the streets, and the streetcars would run 24 hours, every 5 minutes during the day, and every 20 minutes at night. In bigger cities, el or subway trains would supplement the service, with a similar schedule.
Prostitution would be fully legalized, and there would be government-funded brothels for those individuals who cannot afford to pay. (Maybe Victoria's Secret can be legal after all?) There will also be an online database with information about every prostitute. On a side note, such a database already exists for escorts.
All drugs, except stuff like heroin, cocaine, and crack would be legalized. After all, people deserve to feel enjoyment in one way or another. In addition, all drugs now sold only via prescription will be openly available in pharmacies. (Vicodin, anyone?)
Bullying would be punished very severely. Schools would be rigged with a massive camera network, where every little corner is monitored. Anyone bullying another student would be caught and prosecuted. Students would be allowed to bring a tear gas spray and a body alarm to school. Armed security officers would patrol the heavy bullying grounds, such the cafeteria and the yard.
Divorce would be illegal for people with children. It screws up way too many kids, and often leaves the ex-husband penniless. All marriages will require signing a federally enforced pre-nuptual agreement.
