In order to know the answer of this question, let us try to understand the consequence, if we are not polite and honest.

The opposite of being polite is to be rude, impolite, disrespectful, hateful and mean.

There is no doubt that you can neither be happy nor you can make others happy by practice the opposite of the virtues of politeness.

The opposite of honesty is lying, untruthfulness, corruption, deception and cheating.

I am sure that you don’t wish to be identified by any of the above adjectives.

It is always nice to be nice and known to be a good person whom people love, admire and trust.

You can make lots of money, impress strangers with your achievements by being rude and corrupt, yet you can’t fool yourself and the people who knows you closely.

If you are rude, mean, corrupt and cheater, even your family and friends would develop contempt for you and they would discard you forever from their heart.

You may buy artificial respect and honour by your rudeness and corruption from the artificial people, but even they would discard you like a tissue paper after your usefulness is over and your wealth and power is gone.

The virtues of politeness and honesty are necessary to be a good human being and they can never become outdated in any part of the world in any age.
