I am new to Kiva and I can't say that I share your indignation with the process.
I can think of a few reasons you shouldn't be so concerned about this.
First consider that based on the market situations in this countries, there may not be other lenders that want to enter this market for less than 50% interest rate. I've recently returned from Turkey and they're annual inflation is such that home mortgages have never exitsted until only recently and now they are 5 year term and upwards of 20%. So we can't impose our own social norms on other economies without considering the realities. Also consider that these people borrowing the money are capitalist minded in their endeavors. One guy in Azerbaijan that sells clothes may be borrowing $800 to buy clothes that he will then sell for $2000 so his mark up to the end consumer will be higher than 50%.
Secondly, consider that everyone is motivated for some self-serving reason. We may not lend $25 at a 50% interest rate but surely we are deriving some sort of satisfaction in helping someone. So what is more selfish? Lending someone $100 and asking for $150 back or lending someone $100 and getting invaluable amounts of self back patting in return?
Your position reminds me of the many situations in which, we as Americas impose our standards on others to their detriment. For example, the closing of a factory in southeastern china because NBC Dateline ran a story that Nike was having 14 year old girls work 10 hour days, 7 days a week and only paying them $1/hr. We don't take into consideration it may have been the best paying job available to these people and now that we feel good about ourselves for shutting the factory down.......the former young employees have moved to Thailand to work in the sex industry as their only alternative.
Hey Gumby, Pokey here....
"is kiva a scam?" well, I Think RichardF has the best answer for you and hope he does take the time to discuss this question.
I've been shocked of recent with the HIGH INTEREST RATES as well. KIVA has a lot of money to offer to MFI's, I wish they would show their backbone and 'mandate' instead of continue to focus on growth. This also goes along with KIVA needs to focus on 'in house' issues instead of growth (such as accuracy on their website, monitoring MFI's better, etc.)
edit(actually they could be doing just this, but i'm not aware of any interest mandates or strong push to MFI's)
Let's hope KIVA does before some of us give up - and word get's out why. In the meantime, we can hunt for the lower interest rate MFI's to do business with.
