We can help many people in the poorer countries of the world simply by encouraging better farming practices (see the video below).
But what is the best way to help the poor in the developed world? Is it through the work of individuals, private charities, and religious organisations? Or is it through the government? Or perhaps both?
"The road to hell is paved with good intentions."
Much harm has been done to the poor by those who set out to help them. It is simply not enough to have good intentions; we must look at the results.
Before approaching any government representative, it would be wise to see if such a policy has been implemented elsewhere. What were the consequences of that policy? Did it work in the short term but not in the long term? Perhaps it took a while to see the benefits? Perhaps it never worked and in fact made things worse?
In the book Basic Economics, Thomas Sowell looks at various policies which have been implemented around the world and what effect those policies had, especially on the poor. If you want the government to implement a specific policy, I strongly recommend reading that book first.
