@pluralistic Let me rephrase that:
They are locked in because they lack perspective and self-discipline and because their dopamine loops have been hacked by evil techbro sorcerers who used Big Data to fashion history's first functional mind-control ray resulting in real, material things.
They are locked in because actually they don't care because they lack way to much perspective and self discipline and are way to happy with their dopamine.
They are as locked in as the bodies in matrix movies that provide the system with energy and sustain the system with their energy. They are their self fulfilling prophecy, because they don't care enough, they don't understand enough and they never experienced the alternative.
They are as locked in as Germans were in their society in 1933 and as we all are in our consumerist customs and daily life in the face of climate change.
And that's why this whole discussion ultimately is kinda senseless and useless because what climate change will impose on the societies will shadow everything you (we) can imagine.
They could work on plan B and leaving step by step, building up first the alternative till they come to the tipping point and than move ultimately.
But, they wont because they are way to hypnotized and "programed" by their acquired customs. Even choosing bluesky as the option just proves that point again.
As Malcom stated, they are "house negros".
