It is not about parents.
A "nanny state" is defined as a state that is not holding inviduals responsible for their own mistakes.
That kind of tendency is visible in one way or another in most countries.
One good example from Australia folliwing the 2008 financial crisis.
To counter the crisis, stabilise the economy and at the same time invest into a sustainable future, the government had created a "home insulation program" where so far homes without insulation could get money from the government to put in insulation, in the hope of reducing heating/cooling costs in the future.
Now many new companies were created which specialised in insulating houses, among those many small businesses where people were essentially self-employed and just wanted to make money. Unfortunately some were actually not very smart and just nailed or stapled insulation material into the attics without first checking that there were no power lines in the way. And a few people died from electrocution.
While I would argue that when you carry out such work, you better should know about such basics. But the opposition made a big deal out of that and attacked the government, that it should have protected these people from their own stupidiy (as I would describe it).
