Because, as in everything, there is a trade off. Compiled languages are infinitely more flexible; look at Visual C++ for example. However, they are also much more difficult to learn and impliment properly. That same VC++ doesn't have a learning curve, it has a learning vertical line.

A lot of times, developers don't need the speed of a true compiled language. Most apps don't unless they are math or graphics intensive. Therefore, most are better off having an easier time building an app with a few inherent limitations. In addition, in VFP's case, the focus is on the speed of data manipulation, not on the user interface. If you want to build a game, use VC++, if you want to write a general app, use Visual Basic (also an interpreted language), if you want to write a data-centric app, use VFP.
