I think we should get interest for the tu we put in the bank.

 I don't know how much I have to clarify about what it means, but an idea for that the more tu you have in your bank account, the more interest you get per week.

I dunno, should it be week/day/month?

I think week sounds reasonable, while day seems like too much. Month seems far too long for me, but please do comment if you think month is better.

Feel free to elaborate on any specific ideas you have!

I agree, week sounds pretty good.  I thought they gave you an option for that when you open your bank account though?

I've taken this idea up with Pat in the SB before. He said it wouldn't really help the economy, but I still think it's a great idea.

Support.

I don't believe this is a feature that will be added back into the game. At one point, you did have the option of signing up an interest-bearing bank account but it hasn't worked in over two years, and I'm fairly sure I've heard Pat mention that it won't be carrying over into future versions.

We have nifty things like stumbling upon random piles of TU though, and those would generate more TU than interest on banking would by far. =) [Ever looked at a savings account details and the interest it generates? Its like, 3/10ths of one percent, ridiculously small lol.]
