The “Nanny State” concept (I have not read the book) is that some people in government have taken on themselves the task of telling the rest of us what to do; often with ideal intentions but also lacking in common sense. They do not pass laws that are general guidelines, they pass laws that micro-manage us, our kids, our behavior, etc. When the inevitable exception arises, these same people excuse the perpetrator IF the person accused is of their ilk, a particular subset of society, etc.
The Nanny State wants to control our kids from age 3-18. They want to control our health care system. They want to take our money so they can “redistribute” to others.
If you are so interested in “helping” others by giving them ________ versus helping them to learn and earn, why not just give them money from your pocket? I prefer to select my own donees.
Micro-managing (such as the dog house) identifies people who either cannot see the big picture or are so busy looking at a huge big picture solution (for which they will not be held accountable b/c the solution will take decades to show results - think global warming) that they totally miss the fact that humans are quite capable of making good decisions, again IF, they are given enough data from multiple points of view. The filtering of politically incorrect information leads to stupid and bad decisions, as well as micro-management.
