You're fixated on the politicians and they will not change unless a sufficient number of them are voted out office and those remaining change their ways. It is the voters who must understand why polticians habitually lie. Voters make their own rationalizations for continuing to vote for a politician with much seniority, even when that poltician goes mostly against the voters interests.
The voters have to understand the whys and then act upon it concerning the politicians who ignore voters except when up for reelection.
Politicians lie. For many, its their only “skill”. Its what they do. The type of person who goes into politics, with its horse trading culture, is inherently a deceptive person who like the perks of office and the feeling of power. Instead of producing useful goods and services and being held to performance standards to survive, like most people are, they are like termites who burrow into the government and feed from its trough of taxpayer money.
I’m not fixated, I’m just recognizing reality. You even acknowledge that “politicians habitually lie.” Politicians are what they are. They are inclined to do what benefits them personally rather than produce the results that the electorate wanted them to produce. Trust me, I’ve seen it first hand at high levels.
So if I hire you and you don’t perform as expected, you’re gone. It doesn’t matter which combination of 101 excuses it was, you didn’t produce. Just like in our personal and business lives, money talks and BS walks.
