Yes, it is fair. Younger people (Below 18) need to focus more on school. Work can take their attention off of school. And without school they wont be able to get a better job. Plus younger people can only work part time due to child labor. Most workers below 18 also have parents that's job is to feed and care for them, which means they do not even need to work until they are over 18. most people that work under the age of 18 is just for the fact of having money, not because they need it to live.

Answer:
The correct answer is inertia.
Explanation:
Inertia is called in physics the resistance that bodies oppose to modify their state of motion or stillness, either to alter their speed, their course or to stop; although the term also applies to the modifications of your physical state.
A body, thus, requires a force that overcomes inertia to alter its trajectory, which would otherwise adhere to the laws of uniform rectilinear motion, or to initiate a movement, otherwise it would remain at rest. This, of course, considering that there is no rest or rectilinear and uniform movement in the universe, except based on a reference (observation) system. That is why it is preferred to speak of "relative rest."
