College can be expensive, but the most costly aspect is often not discussed. No, it’s not tuition. Not room and board. It’s not even books, though as someone currently in graduate school, I’ve found this can be a little a startling.

There are two kinds of people who go to college – those who have just finished earlier school, for example, high schoolers heading for an undergrad degree, or recent college graduates going for a graduate degree. And then there are people like me, who returned to college after a long break. Each of these types of people has options available to them, to go to college, or to wait, and go to work.


Those born in the mid-1970s will see the world’s population double in their lifetime, from 4 billion, in 1974, to 8 billion, in 2023 (Worldometers, 2017). There is no shortage of discussions on what the maximum sustainable population of the world is, but two things are not debated: Our world’s population is growing at an unprecedented rate, and we need to further increase agricultural production capacity. Our current food production practices will not keep up with the growing demand. Our inability to increase production levels in pace with population expansion is a growing problem, caused in large part by the slowing rate of yield increases due to technological and scientific advancement, environmental issues such as weather patterns, and waste due to poor infrastructure and corruption.
