I'd enforce equality worldwide with same rights for every decent person.
I'd develop new jobs and new industries so there are more options for people out there, plus provide extra training programs for people to have a better chance in getting a job.
I'd make sure that there is compulsory rehabilitation, re-education and re-homing for homeless people and homeless drug addicts.
War would not be tolerated and anybody continuing unlawful warfare would be imprisoned.
More money would be pumped into schools to ensure a knowledgeable society.
Religion would not be a part of government and would not affect any governmental decisions.
Religion would also be taken from schools as it's causing way too much segregation and conflict. It can be taught as a subject, but not control the schooling system.
Proper Taxation would apply to even the rich.
I would designate more land to wildlife reserves and forestry and enforce a non polluting attitude to industries.
Solar panels would be incorporated onto most existing houses and businesses and any for every new building built it would be compulsery.
Oh God the list goes on...
