There are a few interesting passages in 1 Timothy 6 on this subject:
6But godliness with contentment is great gain.
7For we brought nothing into the world, and we can take nothing out of it.
8But if we have food and clothing, we will be content with that.
9Those who want to get rich fall into temptation and a trap and into many foolish and harmful desires that plunge people into ruin and destruction.
10For the love of money is a root of all kinds of evil. Some people, eager for money, have wandered from the faith and pierced themselves with many griefs.
11But you, man of God, flee from all this, and pursue righteousness, godliness, faith, love, endurance and gentleness.
...
17Command those who are rich in this present world not to be arrogant nor to put their hope in wealth, which is so uncertain, but to put their hope in God, who richly provides us with everything for our enjoyment.
18Command them to do good, to be rich in good deeds, and to be generous and willing to share.
19In this way they will lay up treasure for themselves as a firm foundation for the coming age, so that they may take hold of the life that is truly life.
When the Bible talks about material wealth, I cannot see it suggesting anywhere that God "wants" us, as a universal rule, to either be materially poor or rich. Instead I see it asking that whatever your situation is, how does your life demonstrate that pursuing a life as a disciple of Christ is your priority?
