The world has gotten to that point in which every product should have a particular price is been sold for.
A product that is been sold for $5 in USA should also be sold for $5 in Canada and China,
And your reasoning is very funny.
Tell us how you are going to adjust the price in every part of the world so that every product costs the same.
Well, the same product can't cost the same everywhere, because the price is formed from supply and demand, and demand is different everywhere and so is supply. For example, ice cream in hot countries will be in enormous demand, while in cold countries no one needs it. Also, products differ in the degree of availability in each country. For example, bananas do not grow in Canada, which means that it needs to be delivered there, therefore, the price will increase due to logistics, storage and other overhead costs, which will differ from the cost in South American countries.
this way it will help the world leaders to remove hunger in the world,
World leaders are more concerned about staying in office longer than solving the hunger problem of others.
The same price for a product will not increase the quantity of that product in the world. How will this solve the problem of hunger?
it will also help grow the economy of every country because countries can buy product from one another at a better price,
What kind of more favorable price are we talking about if, according to your concept, the price of products will be the same everywhere without any margin?
this method will really help in reducing suffering in the world because hunger is one of man's major problem.
Your method will only create more suffering for everyone.
The world leaders should sit and implement this policy
World leaders can't agree on simpler issues, let alone this.
every product will be given a price that will be comfortable to every common man in different countries of the world.
This is an unrealizable utopia.
