Which country has to support the person who is unable to fulfill their basic needs?

No Country 'has' to support the person who is unable to fulfill their basic needs. Governments do not as well.

Socialist's will explain that they do, but in reality they do not. They take from the producer to give to the non producer, which creates more non-producers until there are not enough producers to cover and the government collapses or moves to the next step which is communism.

Communism will explain everyone get's equal shares, but throughout history in communism the government gets most of everything and the people get little. Also in communism every time it has been implemented the leaders have murdered through starvation, assignation or killing 10's of millions of their own people to get the people to do what they want.

Capitalism works best for the producer, you work hard you get ahead. But, it is bad for the non-producer, you don't want to work you have nothing. This is where faith or Religion step's in with Capitalism, as each is 'personally responsible' they are able to lend a helping hand to those less fortunate. This way keeps the government out and those that can, give what they are able to.
