It is impossible to create a world free from poverty. Jesus said, "The poor will always be with us." This is true, in every sense of the word. In a neighbourhood of millionaires, won't someone making $70,000 (in American dollars) be considered destitute? Yet, $70,000 per annum income is more than most people make in America.
Poverty is relative. But it is possible to reduce the suffering and improve the appalling conditions in which the world's most destitute live. I believe that introducing capitalism to those regions, and the philsophy of rational egoism will help solve the problem. Educate the people, and foster a hunger for knowledge in them that in turn will ease the hunger of their bellies. Create a strong middle class, and abject poverty will become almost non-existent.
There has never been a famine in the history of the United States; pandemic disease is a thing alien to most Americans. That is because of the philosophies upon which America was founded: rationalism, individualism, and freedom of thought, speech, and expression. If you can introduce these philosophies into some of the world's most destitute regions; if you can introduce moderation and tolerance into the religions practised in those areas, then perhaps you can wage a successful war against poverty.
Although such a thing would never happen everywhere, although it is possible in some regions. Why? Because were equality, justice, tolerance, and rationalism to be brought to such regions, those who currently hold the power will find themselves at the bottom. As the current leaders will be very unwilling to allow anything that will cause them to lose their power, it will be Herculean, if not a Sisyphean task to change the negative cycle of life in the world's poorest nations.
In short, there will, there must always be someone who is poorer. But perhaps there need not be abject poverty everywhere.
