Answer:
Employment allows you to provide for yourself and your family. With employment, you are likely to have your basic necessities covered, like food, utilities and housing.
Employment makes you feel useful in some way, makes you feel as a contributing member of society, a feeling that helps you increase your feelings of self-worth.
Finally, employment helps you plan ahead for the future. If the employment pays well, or if you manage to spend less than you earn, employment allows you to save money, which is the first step in building a personal equity.
