I'd really prefer some number Tarub. Other commentary is welcome, but at least my point of this thread was to get an idea of what numbers most people felt were appropriate growth rates. You don't even have to know anything detailed about each topic, just whatever feels to be the right amount.
I think the problem with that request is that these numbers are all going to be relative to some other factors. There's an interconnection between interest rates and inflation, for example. So a rate that would be quite reasonable in one economic situation may be either highway robbery by the credit company in another, or result in guaranteed losses for them in the other direction.
Ideally, inflation should be in the sub 3% range (yearly, not sure why you asked for monthly rates). A reasonable interest rate for a "normal" loan should reasonably be 4-5% higher than than. However, what is normal depends on the risks involved. Credit cards are considered high risk. Very high risk. There's a ton of fraud and people who just don't pay their bills and then walk away from the debt. When you look at a credit card charging you 20% interest on your debt, that's because you are paying for all the people who rip off the companies and/or declare bankruptcy on the debt.
A more reasonable question to ask is: What should the yearly net profit ratio for lending institutions be? An a "reasonable" amount would be around 5-10%. Some of them make more than this, some don't. I don't recall the industry rate at the moment, and don't feel like looking it up, but IIRC, the highest profit rates were for technology companies, the lowest were retail, and banking was somewhere in the middle.
The population question is flawed because you're asking people about growth in their town, but then equating that to total planetary population growth. Most of the posters here are going to be from 1st world nations, which traditionally have reasonable population growth rates and are not suffering from overpopulation. It's the same sort of mistake we see all the time when people talk about implementation of environmental regulations in the first world, while ignoring how this fails to address (and in many cases make worse) the situation in the rest of the world where the real problems potentially are.
But yes. Global population growth needs to be slowed down. The trick is how one goes about doing that. It's particularly hard to tell people not to breed. And one of my own pet theories is that breeding rates of all creatures tends to increase when they feel their resources are limited (survival instinct. Outbreed the competing species for the same food/water/whatever). So we're potentially doing exactly the wrong thing with all the food and assistance we provide to regions that physically cannot sustain their own populations. We're allowing them to live in those resource limited conditions instead of suffer the "normal" population limiting factors (yes, I know how this sounds), and additionally they respond to this by
increasing their procreative output when they should be decreasing it.
I'm not sure how the medical costs question factors in at all. Obviously, costs should not become relatively higher over time. But just as you can't look at "acceptable" values in specific places and times in terms of population growth needs, you can't look at single trends here either.
