In a way, these might be modern variations of the old Paradise myth; the romantic idea that in the past there was a time when things were good and pure, and then a mistake happened and things started to go worse and that's why the world of today is troubled. And then different traditions have different views of;
1. what exactly was the Good Original order of life
2. what was the mistake and when it happened
3. if there is anything we can do to correct the mistake and to resume the untroubled good times.

Or, seen from a more psychological point of view - when people have to struggle for their daily survival, they are constantly fighting for a secure, easier life. But once the easy life is secured, they slowly start to feel bored and unsatisfied. Seems like a dose of struggle, danger and sweat is an essential part of healthy life. In the contemporary world people use amusement park rides or extreme sports to get their dose of danger and thrill. They build careers or have DIY hobbies to get a sense of effort and accomplishment.

But, yes, I'm afraid that a lot of politics is about using slogans to fool people to support things which they actually don't like. (And, as always in politics, everybody says that they work hard for good things. Only that they have differing views of what 'good' means when it comes to details)
