First, it's a meme. The context is the grandma is of the generation since the meme is a known thing. It's not specifically calling out grandmas. That seems a bit lost on you.

Second, they did make the decisions we are currently in and fought to make it conventional knowledge. They allowed the mechanisms of balance within the government to go so far off the scale that coming back it so daunting I am not sure how it can get there.
