Economically, can there be a way people can live and no one will be poor?
No its not !!!
Imagine if everyone is almost living n good condition and there will never poor, who will serve the other?
i mean who will be needing to be slave or workers if we are having the same lifestyle?
there must be poor so there will be rich and Middle.
this is how the world works and that will be the lifestyle forever.
I think poor is not like that, poor is not enough, unable to meet daily needs. that's poor in my opinion. and that of course can be overcome in this world by each country.
and if it's like you said, it's definitely not possible. if everyone had money then life wouldn't go on anymore. we all have different standards of living. everyone stays in their respective professions and has enough to make ends meet. Of course it will happen if the leaders in this world can be fair and willing to do it without any exceptions.
