I was studying business as defined by the terms of being able to apply for government support. Do you work in a business?
I work in food, so I suppose that could be considered a business. I am studying at school to do Engineering in the future, however. 
That's cool. Do you want to work in a small Business, or a privatly owned corporation? Like own your own business?
Probably a small or large business in the future. I'm not particularly interested in starting my own business, personally.  
Given the economic history of the United States and the characteristics of their developments, you should do well in engineering.
I hope so as well. I'm fortunate enough to have not had to take out any student loans, and am going to hopefully be able to graduate college completely debt-free. 
That is a great advantage. Debt for students has grown rapidly since 2006, rising to nearly 1.4 trillion by 2016.
That's crazy. Do you recommend starting a business or going into one
I recommend the best sector based on the highly developed mixed economy in the United States. 
What is the best sector?
