>they overlook the additional problems they've created

By making food cheap, we have created a society that suffers from obesity. But 100 years ago (and at all times before this, excluding a few random lucky individuals) people were suffering much, much more from a want of food.

So in a sense, yes, we have created a new problem. But that was a consequence of solving an other, bigger and much more pressing problem.

So, to be honest, I don't give much for "engineers overlook the problems we create".
