One
of
the most basic concepts of economics is want vs.
need.
What
are they exactly?
A
need is something you have to have, something
you can't do without. A good example is food. If you don't
eat, you won't survive for long. Many people have gone days
without eating, but they eventually ate a lot of food. You
might not need a whole lot of food, but you do need to
eat.
A
want is something you would like to have. It
is not absolutely necessary, but it would be a good thing to
have. A good example is music. Now, some people might argue
that music is a need because they think they can't do
without it. But you don't need music to survive. You do need
to eat.
These
are general categories, of course. Some categories have both
needs and wants. For instance, food could be a need or a
want, depending on the type of food.
You
need to eat protein, vitamins, and minerals. How you
get them is up to you (and your family). You can eat meat,
nuts, or soy products to get protein. You can get fruits and
vegetables to get vitamins and minerals. You can eat yogurt
or cheese to get other vitamins and minerals. You can eat
bread to get still more vitamins and minerals. These basic
kinds of foods are needs.
Ice
cream is a want. You don't really need to eat ice
cream to survive. You can eat it to get some vitamins and
minerals, but other foods like cheese and yogurt give you
more of those same vitamins and minerals without giving you
the fat that ice cream does. Still, ice cream tastes good to
many people. They like to eat it. They want it, but
they don't need it. They like it, but they don't have
to have it to survive.
OK,
we've covered food. What other kinds of things does your
body need to survive?
