I believe nature is fair to all and while it gives some people that quality, others can bank from these brilliant ideas and bring it all to reality by supporting the ideas with the needed finance, resources, and coordination required to have a successful firm.
Nature might be fair, but most people who do that aren't fair because what they do is they take the ideas from people who aren't able to convert them into reality, use the resources and everything they have to bring those ideas into life but don't include or give credit to the ones who the original idea was from. I have seen this happening on a lot of occasions where one person shares his business ideas about what he wants to do and another person listening to that steals the idea and starts the business before that person could do it. That isn't fair, is it?
I believe people who tend to have a lot of great ideas and plans about businesses or anything can't bring them to life because of a lack of resources like having enough money to fund the ideas or have any reach or anything to get things started if it requires legal processes and everything, but on top of everything, it's mainly all about finances.
Its so rare to find someone who bank on someone idea who is not fair. Most times it depends on the agreement of the one with the idea. If he chose to have an equity for whatever they realize in the business or investment. But lets look at it on a brighter side. One has the money to bring that idea to life and the other has the idea but dont have anything. At the end it is the one with the money that needs to have a say because he is the one fulfilling the dream of the other one. If not such dreams will pass away after the death of the dreamer.
In my opinion whatever the one with the idea should work in the business, because since he came uo with the idea he would be the best person to manage that business or investment to become successful. A negotiation or agreement should be made in terms of finance so that everything would be fair thereby benefitting the both parties at the end of the day.
