The reason that liberals promote change is that they care. Its also because they have the flexibility to cope with change. They are not afraid to make a few sacrifices if it benefits society as a whole. They understand that to think beyond the box is the way to creatively solve problems.

Conservatives are full of fear. They are afraid of change because it might disturb their comfort zone, they might have to sacrifice something. They are dogmatic because it doesn't require thinking. Its easier to follow orders than to problem solve effectively.

The only way to survive is to embrace change. There is nothing more American than that.
