Because we are not living in ideal word.

i agree with every point in that paragraph.

I don't agree with global level. Nations has different wealth, different technologies, etc. You cannot apply same rules for US or India

with traffic rules i meant the general stuff, like on which side to drive on, the colors of traffic lights, the design of street signs. those are pretty much already a global standard, and rightly so. because it does not make sense to have those work differently in different countries. of course there should always be carveouts for regional specifics. we don't need kangaroo warning signs in austria.

other examples are things that are for the most part already global standards. like the metric system. yes, the US should literally be forced to change here. it's become the laughing stock of the world on that issue. also copyright law. etc. money should be global. we don't need different currencies. maybe punishment for serious crimes. human rights. but on the other side there are many things that are global or almost global now, that should not, or need not be.

Same for pollution. For example US made huge capital on pollution in 20th century. Would you ban developing country to obtain their capital from pollution today and made similar wealth as US previously?

well, yes and no. i agree with you that it is not fair to just stop everyone from polluting when their economy depends upon it. but as pollution is destroying our climate, we have to do something about it. we can't just allow some areas to pollute the world while other areas don't. it would not work. what would, and does happen is that that those countries that decided to limit their pollution just export their production to pollute elsewhere.

what we do need to do however is to then enable other ways for these countries to prosper. we need to invest into those countries and build them up much like we built up some countries in asia and europe after world war 2. see more discussion on that in the thread on chocolate here:

I would like to free ourselves from the idea of needed rulers above our lives

agreed. partly i see this as a historical problem. we started out with rulers being absolute, like kings, etc.

eventually some started to elect their kings. etc. you know the history. that history is the reason we look at elected leaders as rulers above us.

so we need to change the understanding. that those elected representatives are there to serve us. not we serve them. their responsibility is to take care of our problems, and find and propose just solutions and rules for us to be able to live together.

there are a few things we can change to make the election system fairer:

first of the whole party system is designed for conflict and not cooperation. get rid of it.
each representative should be independent. no more toeing the party line. make decisions only based on your conscience.

next point is a bit harder: get rid of the concept of candidates. don't allow election campaigns. don't allow media to promote certain people. let people get elected only based on their reputation as good citizens. this prevents influence of the elections by those who have more funding.

but that only works in small communities, where people have a chance to know each other. for big cities that practically means elections per neighborhood.

elect multiple people per neighborhood. also give each person multiple votes. maybe as many votes as the number of people to be elected. multiple votes avoids that a majority of votes concentrate on a single person. because everyone has to still assign the other votes they have.

these are then the community/neighborhood representatives, and they make decisions for their neighborhood.

elections on a higher level are made from those elected at a lower level. all the way to the top. this levels the playing field and it allows good people to become elected without financial resources.

i don't think a perfect system is possible. but this system would remove a lot of friction, combined with favoring decisions at a local level, it would be a lot better than anything we have currently.
