Some kinds of berry bushes have good tasting berries and some bad. The birds eat the good berries in summer and fall. When winter comes the bad tasting ones are still left so they have something to eat to survive till spring.
Again, the devil taketh him up into an exceeding high mountain, and sheweth him all the kingdoms of the world, and the glory of them; And saith unto him, All these things will I give thee, if thou wilt fall down and worship me. -Matthew 4:8-9
If someone were to ask me for help to feed his family or for medical care I would not loan him the money but give it outright. There are many worthy charities that do this. On the other hand if someone wanted to invest the money to make more money it would be better to loan it. That would get him working and after it is paid back the money could be reused to make more loans. That is what Kiva, http://www.kiva.org, is all about.
We hear a lot about "Wall Street" and "Main Street", but how about "Industrial Avenue"? When money is made by investing or loaning it is usually taxed at around 15% (capital gains tax). Yet industrial production is taxed, in most cases, around 35% (corporate income tax) and then taxed again when it is distributed to the shareholders of the company. No wonder the majority of business majors are now looking for jobs in finance not manufacturing. People complain about exporting jobs. How about cutting the corporate income tax? That would help a lot. p.s. I'm sure lot of Muslims are feel vindicated by the economic meltdown, since their religion forbids loaning money for interest.
