i think this what Islam calls for:
59:7 (Picktall) That which Allah giveth as spoil unto His messenger from the people of the townships, it is for Allah and His messenger and for the near of kin and the orphans and the needy and the wayfarer, that it become not a commodity between the rich among you. And whatsoever the messenger giveth you, take it. And whatsoever he forbiddeth, abstain (from it). And keep your duty to Allah. Lo! Allah is stern in reprisal.Quran
If you ponder in
that it become not a commodity between the rich among you). one understand that people should share the bounties of Allah swt ......It is unfair that only a small number of people enjoy the big wealth while others suffer .......
The economic system in Islam does not allow such differances between people ........
3:130 O ye who believe! Devour not usury, doubled and multiplied; but fear Allah. that ye may (really) prosper.
2:215 They ask thee what they should spend (In charity). Say: Whatever ye spend that is good, is for parents and kindred and ORPHANs and those in want and for wayfarers. And whatever ye do that is good, -(Allah) knoweth it well.
2:177 It is not righteousness that ye turn your faces Towards east or West; but it is righteousness- to believe in Allah and the Last Day, and the Angels, and the Book, and the Messengers; to spend of your substance, out of love for Him, for your kin, for ORPHANs, for the needy, for the wayfarer, for those who ask, and for the ransom of slaves; to be steadfast in prayer, and practice regular charity; to fulfil the contracts which ye have made; and to be firm and patient, in pain (or suffering) and adversity, and throughout all periods of panic. Such are the people of truth, the Allah.fearing.
