When you lie all the time, you assume that everyone else is lying all the time. The president rewards praise, not the truth. So if you work in the White House, you lie and praise the president, you tell him what he wants to hear instead of what he needs to hear. Effective policy, however, is not built on falsehoods. Sooner or later, for example, the water rises, the streets flood, property values decrease and your line about climate change being a hoax is no longer relevant to reality and you are no longer relevant.
