In many industries and fields, speaking the truth isn't well-received because lies align with the beliefs of the masses and serve the interests of those in power.
You're right, many tends to bend away from aligning to the truth because money, influence and power are all involved, you should check on any sector now, you will discover that once money is being involved, people will behave in strange manners far away from the truth, which is not supposed to be, all these are what sum up to corrupt practices by the people in the society we lived in today.
I think we are in the world whereby people worship money because they see money as everything. Things have really change before now you can hardly see people who are interested in money over saying the truth, this is what corruption have turned people into that they can't stand for the truth because of what they will gain in doing the wrong things. Corruption is turning the society into something else , thst people will be so comfortable to lie to gain selfishly.
