"Assuming, naturally, that one has the skills/education/capital to do so."
So true, and that has so many ramifications. All positive. For instance, it is a giant incentive for us to maximize our skills and pursue our education; to capitalize ourselves.
We are rewarded, for example, for delaying gratification. My son lived on peanuts with his parents (!) and studied and worked very hard, about 500 hours for free doing pretty gross stuff, to get his EMT certification. Why? He was sick of working at, literally, McDonalds. Low pay, uninspiring work, ill treatment from customers and management, no future. Because those with skills, education, and capital are usually rewarded, he worked hard to improve his skills and education. We supplied, by God's grace, as called as we are as parents, most of the capital.
As I home school our children we supply oceans of educational capital, equipping our children to earn the best living they can as they become adults.
Some "skills" are so very valuable, and require no degree. When I have been in a position to hire, it was very difficult to find people who were PUNCTUAL; HARD WORKING; POLITE; DEPENDABLE; and above all, HONEST. Such an employee is gold. So we are incentivized to increase these graces in ourselves as well.
Further, as parents, as church bodies, and as philanthropists, we are incentivized to educate our wards, capitalize them as appropriate, and develop their aptitudes into useful skills. This is also very commendable behavior.
Finally, we are called to charity towards those who, through no sinfulness of their own, can't be very productive, for example the mentally challenged. Again, very positive.
