Less consideration, more egoistical survival.
Yes. The ego - the "this is who I am" mentality, without actually exploring if that is actually the truth.
Also, there are many exterior influences that can force us to raise our children differently - economic and social status, for example.
A child brought up with a scarcity mindset might become more successful financially than their parents, but is that success limited by the original anchor? Is it comparative success rather than reaching full potential success?
You know the story of why there are so few taxis in NY city when it rains? Because people take taxis more, so the taxi driver makes their quota (anchor) sooner than normal, and goes home early. There are literally fewer taxis on the road. However, a smart taxi driver would make hay while the sun shines (or while it rains in this case) and work longer, so then on the next sunny day when everyone is out happily walking to work, the tax driver can have a day at the beach instead of waiting around for fares.
That depends on the case. The scarcity mindset can have several reasons - as you write, one can act decisively against parental anchors, or accept them. And there are probably a thousand nuances. The person can come from a greedy family as much as from a very poor family. Different backgrounds causing the same issue.
For the NY taxis: Yes, sure. There's also the story of the fisherman lying at the beach chilling after having caught enough fish for the day, and the business man coming up and telling him how he could make so much more money if he kept fishing and then enjoy life. But the fisherman is already enjoying life.
It depends on what the driver or the fisherman want in that moment. Being home early with the family and enjoy a nice dinner or board game during the rain has something, too.
Yes. This is human nature. However, in that moment we aren't very good at predicting how we will feel in future moments. Should children eat what they feel like in the moment? Should adults do what they want in the moment, even if it is harmful? We all live in the moment - but each moment doesn't have to be a nail in our future coffin.
Also correct. It doesn't have to be. In your example, it's either going home early and doing your job regularly on a sunny day, or preferring to keep working and go to the beach on that sunny day. It's a choice to be made, and that's what I refer to with "want". People make choices. The important part is to be conscious about the choices, like the fisherman. He could work more and retire early. But he chooses not to.
That's something we can do as adults, as we are responsible for the consequences. And that is what children have to learn, to be able to make decisions and stand up for them, taking the responsibility for them. If we as parents actively choose our parenting style because we're conscious, then yes, it's probably not perfect, but there is at least a line to walk, it's not instinctual, but based on a decision that we can defend in front of ourselves, and later in front of our children when they come and ask us why.
