I think there are plenty of startups working on valuable things, but since you mentioned education... Typically, the largest group of students in open online courses like MOOCs are those from privileged backgrounds, like white males, and those who already have high or relatively high levels of education. Certainly, I still believe that these online courses are an amazing resource but they haven't been shown to increase access in ways that people hoped. There are dozens of reasons for this. I think the real problem is that some startups are unable to recognize exactly what problems they are solving and for whom they are solving them. Extra disposable income from driveways is good, as are promoting healthy drinking habits. However, there's a very real chance that these potentially useful tools never reach the audiences where they would be most impactful. For example, it seems like the people who could most benefit from extra income from rentable driveways are most likely to live in areas that are less desirable (high crime rates), are not even likely to have a driveway (apartments). Now, I have no idea what app this even is referring to, to be clear. This is just a potential situation.
