It is January 1st, 2018, you just turned 20-years-old and are a high-school (only) graduate working only 40 hours per week (playing video games for the remainder of the week), and earning $14 per hour. It is a relatively safe job (financially) and you plan to work at this exact job for the next 45 years of your life, after which you will retire at the age of 65 (to play video games for the rest of your life.) Now, assume that your salary (i.e. minimum wage) increases by 2% wage inflation at the start of every new year until retirement. Question: You are now considering enrolling in a full-time program of study (BA degree, college diploma, extended technical certificate, etc.) that will require you to stop working for 5 years and pay tuition of $20,000 per year for 5 years. The benefit of this big investment in human capital is that when you graduate at the age of 25, your wage will triple in real terms relative to what it would have been at that age. So, for example, instead of earning $14 per hour (in today's dollars), it would be $42 per hour, in today's dollars, etc. What is the Internal Rate of Return (IRR) from this "investment" in education? I would like to see (only) two digits (e.g. 4.5% of 45% or -12%, etc.) since anything beyond that is meaningless given all the assumptions you will have to make. Please state very clearly any-and-all assumptions you are making in answering this question. For example: "I ignored income taxes." Or, "I ignored death", etc. Warning: Any implicit assumption that you make - not explained - will result in a loss of points.
