Education is an investment that benefits their own future in the days ahead, because if we are the ones that get higher education, when we were working, we will earn more than the general ones, etc.
Education is an investment that can benefit their own future tomorrow because if we are to get a higher education when we were working, we would be more than the average person and so on.
Education is useful to my future investment in the future because if we are the people who get high education when we work, we have more money than people.
