Solving the problem of one rich person can save thousands of jobs so it depends on who is that rich person and what is their problem.
I would be thinking your view is that the few rich or that rich will help bring out thousands of poor out of that poverty but the majority view of the mindset of the rich is that they don't like to help the poor out of poverty because they want people under them for services they think they have overgrown because of their social status. This factor might disqualify help for a single rich. This is a general view but I believe their are few rich that also want good for the poor.
The view that you describe is examined from the behavior of the capitalists, they do not like to lift the poor for the better or in the same ranks as them if the poor are not useful to them. But not all of their rich people are capitalist and have such a viewpoint, but only a small portion if calculated.
If you see more replies that say to solve the problems of more poor people then its not a wonder because that is the right thing from an ethical Point of View.
It is trite to consider helping the poor for different reasons. At least the number of poor people keep increase and that leads into different vices in the society. The poor with their size if given help means their will be more labour force that will also contribute to the GDP of the country and that will improve standard of living. A poor person has a very good idea of how to better others behind him because he has been there and that will mean more people getting out of poverty than what would have been with helping a rich.
From the conception of ethics is true like that, but that does not mean that poor people who have become better will have a more concern for other poor people, this is relative and back again to those people who can become better at the level of life.
But in another point of view, they do help the rich, the better they work the better also for the owner of the business, and for the rich they are a tool to increase their wealth, this is a reverse thought but is quite logical if seen from this point of view .
