Different things that fix many of our problems:

1. Limit the bulk discount. Reason: The bulk discount destroys small businesses. A small business that can only buy a small sum will never be able to compete on the market angainst megacorps that buy the product bulk in huge quantaties. As an excample a video game costs about 50$ a mega corp buys them for 10-20$ a piece and sells them for 50$.
A small business that would only sell 10 copies would have to buy 10 copies for 60-70$. For a small business to be able to just break even, it would have to buy hundreds of copies which it can't sell. The almost limitless bulk discount enables mega corps and keeps small businesses from being able to compete.

2. A Minimum wage or better unconditional basic income
Reason: The minimum wage is needed to protect workers, there needs to be minimum otherwise people cannot live.
Down the road machines, computer and AI will destroy jobs to apoint where humans won't be able to work at all. Human laborers will be too expensive and imprecise to do the work. Machines and AI will do everything better. Without the unconditional basic income humans won't be able to earn a living. Wich WILL create war.

3. Minimum space per human
Reason: Every human needs space to live and space where food is produced for that human. A country needs to have enough living space and cropland.

4. Worldwide currency and minumum wage.
Reason: Labor should be paid the same and it should not matter where. The differences in currency creates slave countries. With one currency and minmum wage fair trade is possible. It creates a power balance between countries and would reduce wars and poverty.

5. More resources for schools.
Reason: Imagine adding everyone capapble in poor countries to current research. It would boost humanity immensly. We would be able find and do so much more. There are smart minds there that just waste away in menial jobs because they didn't get the right education.

6. Games in schools and kindergardens to school children against "HIV humans". With HIV Humans I mean humans that blend into society undetected and corrupt our political or social landscape for their own gain, like the hiv virus does in out bodies as it is not detected by our white blood cells. These humans destoy any system and the only protection we have is to be aware that they exist and that we can't let them gain power.
Some examples for games that go in that direction: The Werewolves of Miller's Hollow and Among Us.

7. Create an autarkic lifestyle for everyone.
Reason: Politics is corrupt and will fail. History shows us that it always repeats: There is a war the population suffers but starts to rebuild. Things are good but corruption takes place and war breaks out. This repeats every 50 to 100 years. When war breaks out the first non military targets are food, energy production and infrastructure.
If the general population has their own food, water and energy production a war will have a lot less impact on a countrys population.

8. Make forex/stock trading illegal and replace it with croud funding.
Reason: It's not used for what it was created, it's basically gambling addicts that screw with prices of currencies, wares, companies etc. destroying them and more in the process. They cause more harm than any physical war.
