The main reason why lies and hypocrisy is becoming more common, bordering on acceptable, is simply because it is "politically incorrect" to correct liars and hypocrites...
I asked someone once why he told his wife an unnecessary lie, and he matter-of-factly replied "I knew that's what she wanted to hear". His lie made him look good to his wife at the expense of another person, and he made me an unwitting accomplice because I never told her the truth.
Donald Trump is a prime example of a liar and a hypocrite, who tells certain people what they want to hear, and because of that he's become an unstoppable political phenomenon...people get the government they deserve.
Unfortunately, there are too many people who would rather hear a pleasant lie than an unpleasant truth...
