Some people have written about this and what to do about it. Most notably is a 19th century author/journalist/economist named Henry George, who wrote a book titled “Progress and Poverty”. It’s available on Google books, notably in a modernized version by Bob Blake. If you can’t find it, let me know and I will lead you to an electronic copy.

The basis of the idea is that the reason that poverty increases despite the advances in technology, is that land owners, with the support of most governments, are able to co-opt any increase in productivity and so the worker is shut out of the benefit of this increase.

If you look at the history of this country and how European colonists overcame the indigenous peoples and excluded them, not only from any progress, but often from the very land that they had occupied.

Some of my friends have more on line, such as:

I suggest that if we want to do something, in addition to lamenting, that we look into this.

I agree with your statement that God doesn't give us possessions. I think we shouldn't feel guilty about the things we are able to earn or buy, though, and we should use them for the best things we can. My Disciple study group just finished an overview of Luke and we discussed the parable of the “shrewd manager” for a long time. Jesus said the manager was praised by the boss who fired him because he had made good and clever use of the things he has. Jesus didn't say anything about the possessions being “from God.” Instead, we hear, “I tell you, use worldly wealth to gain friends for yourselves, so that when it is gone, you will be welcomed into eternal dwellings (Luke 1:9).”
