Honesty is not the best policy and politics in today's opportunist world?

How far do you agree with that statement? Just consolidate your answer with a lived experience and discuss. So, would we be encouraged to lie even if we are not too used to it in order to succeed in our work in any sphere of life? Honesty is not rewarded today, how far do you agree with this? Liars succeed, nah? So if we are truth speakers, we will lag behind, right??
