Answer to Question 1
The skills an individual chooses to develop in order to earn a living is called human capital. Acquiring new skills or improving existing ones is an investment in the same sense as a business owner's decision to build a new plant. Both will generate income over a span of years. Investments in human capital take place under uncertainty. Attending college allows a student to build up general human capital which can raise productivity in almost any job a graduate might take. More specific choices are riskier, because future technologies and markets are intrinsically difficult to predict.
