I don't think all humans can stop telling lies in the society, because they are part of some of the things they are using to survive in their living, and the reason why I said it, is because as a business man I am, there is no way you can tell your customers the truth about the price of your products.
There are some people telling lies because they are forced to do that because they are under their Boss, which their Boss will tell them to lie for them to achieve their goal which the employee must lie to help his or her Boss to achieve their goal from the business.
I guess there are few people in the society who are not telling lies no matter where they find themselves, and they are ready to lose any positions in the society to remain truthful which I have seen such people around my society.
Do you mean there are more truthful people in this world? I've never seen such people in my society before, because even our elderly people, who we believe will never tell lies, do so to survive in some position. It is difficult to find someone who is not telling lies in today's world, everything has changed, and in some situations, telling the truth will not get you far because some people believe everything that is lying, if you tell them the truth, they may disagree that you are lying to them. However, lies have already become a part of our bodies, and we can't survive without them.
Furthermore, people who lie seem to be business owners. Many business people in my country can increase the price of the goods they have in stock for more profits immediately as they notice that the price of the product they are selling increases from where they are purchasing their goods, and we, the customers, have nothing to do about it because we have no choice but to buy at the price they sell their products.
