Airplanes are essential for modern business operations, which greatly help the economy, and thereby help everyone. We also rely it on many other aspects such as mail service, medication delivery, flower delivery and the list goes on. Just look at what happened to Europe when the air space was grounded for a short week.

Hi... No I don't think airplane is only for rich people these days...

is ok =) any question is accepted

There are low cost carriers all over the world today.

Hello Sophia, It is useful for everyone, but maybe rich people will be able to use it more frequently,so they will benefit more of a quicker transportation mean. As a multipurpose commercial vehicle,it serves everyone, but as a recreational vehicle the richer will gain more of its use.
