What laws would I enact?
Which policies would I enforce?
How would I fix our broken government?
Hmm, let me give it a shot.
1. Every present congresscritter is evicted and all present and former officeholders are barred from public office or working as or with a lobbyist organization for 10 years.
2. Codified into law: corporations are not people, and may not be designated as such without a constitutional amendment. Corporations thus do not enjoy any of the constitutional rights accorded to persons.
3. Any corporation found to be grossly negligent (causing loss of life, environmental/property damage, or fraud) shall either be nationalized or have its charter revoked. Its officers will be charged with a felony and forever barred from being an officer or member of a board of any publicly-traded company.
4. The federal government is prohibited from "bailing out" any company, with the exception that a company be nationalized and disolved over a period of 3 years. Its assets may not be sold to any entity that employes or pays any present or former officer (directly or indirectly) of the troubled company.
5. The DoD (including defense-related line items in other departments) may never make up more than 5% of the yearly federal budget. In the event of war, or other emergency, a draft will be enacted, with no deferments, and a "war tax" added as a national sales tax for the duration of the conflict. No out-of-budget funding for military operations is allowed, except via "war tax".
6. Any high-level government official suspected of human-rights/war-crimes violations shall be subject to investigations and trial in a neutral court, with the penalty up to and including death. Failure by the president to investigate/bring charges will result in automatic impeachment
7. All national laws, treaties and rights apply to all persons physically located within the borders of the US, regardless of citizenship status. Any outpost, base, camp or other location under direct control of the government or government agency is also subject to these conditions.
8. Secret (i.e. FISA) courts are prohibited. All court proceedings of a criminal nature are to be open to the public and are not subject to "state secrets" or "executive privilege".
9. In all cases, without any exception whatsoever, regardless of the crime charged or the defendant's status, designation, or classification, the defendant has the right to a public jury trial consisting of no less than 12 jurors. The jury will be informed of their right of nullification prior to trial.
10. Software is not patentable. All software patents are null and void.
11. The internet is designated a Public utility, not under the control of private corporations. Net neutrality is required for all providers, upon pain of nationalization.
12. Copyright protection may not extend for more than 10 years. The work's creator (and only the creator) can renew copyright for another term for a nominal fee. Upon the creator's death or failure to renew, the work is placed in the public domain.
13. The government guarantees the right of shelter, basic healthcare, sustenance, education and work to all citizens.
There's so much more (wealth disparity, people/companies/sports teams paying no taxes), energy policy, etc, etc that there isn't enough time to list them all... ;)
