Ethical Investing in a Local Area

When my girlfriend and I were in Bali, we noticed that on the street where we were staying, a spa center was being built... but there were already about ten of them on that same street. In Southeast Asia, it’s quite common to have lots of the same kind of business on one street. A little lane for electronics, a lane for fertilizer, and so on. The longer we stayed, the more we noticed that these developments were by immigrants, and it seemed more like an investment opportunity. But what if it would make more sense to build something better and more meaningful in a given location? Based on certain data, the ideal project for a specific area could be predicted.
