Can you be a Dictator for a Day? by the very nature of dictatorship the only way it'd last for 1 day is if you where overthrown or assassinated.
Ok I'm being pedantic.
1 all democratic governments to be replaced with random lotteries, fixed term length 10years
2 All companies to pay full tax by trade done within a country, any company trying to avoid tax shall have asserts seized by the country in question equal to twice the amount of tax avoided, the first asserts to be seized will be shares from board members.
3 Anyone trying to pass off, as there own, things or concepts that already exist by repackaging them and calling it innovation (yes I'm looking at Elon Musk here) shall be tarred, feathered and dipped in raw sewage for good measure.
4 any science reporter/correspondent has to know some science and apply basic scientific thinking to ALL articles. If they just repeat marketing or hype without any form of basic critical thinking then they are automatically volunteered for taking part in well published experiments to disprove pseudo science. (such as the homeopathic curative ability vs plague or gunshot wounds)
