Where can I put my money that won't make me angry?

I don't know anything about them, but could you use an Islamic bank? I think that Sharia does not allow for Usury, so Islamic banks are basically not for profit.

I personally wouldn't since I wouldn't want to sponsor a religious doctrine or organization, but your mileage may vary.

A more sensible idea by far is National savings or Premium Bonds.

Greed (-any interpretation) will out, always.

My own view has always been that usury is immoral, one of the better teachings in the Bible and the Koran.

Sharia - UK Islamic banking (and indeed most - if not all of Islamic banking) - usury / profit (or lack of) = slight of hand.

By way of example. . . . there is a quite wonderful theological/ethical/epistemological/religious/cognitive magic trick performed daily in Iran (I am not aware of how common this is in other Islamic countries) - under Sharia sex outside of marriage is unlawful, but of course human nature cannot (can never) be stemmed so a quite fantastic act is played out on the doors of Iran's brothels ("morality houses") . . .the magic of "temporary marriage" - you - on entry - marry to facilitate prostitution, then once you have fucked, you leave and are divorced.

Similarly Islamic banking in the UK follows a similar slight of hand - the illusion that religious edicts have been followed, interest may not directly flow from unearned sources, but it is re-routed, redefined and renamed in the mould of the better tax magicians.
