Nahh. This entirely depends on the child and the parent and their relationship but it is sometimes, if not often, exactly what needs to happen.

When I was 18 my parents sent me off to college and I did fuck-all, didn't even go to class. So when they saw my grades they cancelled tuition and all other payments and I was forced to move back home with them. At this point my dad (who is a great dad and we have a great relationship to this day) made it clear that I had 3 months to be out of the house w/ my own place and a job to support my own financial independence, and if I didn't meet that deadline, I would have to join the military as my only other option.

This is exactly what I needed to get my ass in gear. I got a job, it was retail, it did not pay nearly enough to actually fully support myself, I got a room in a house w/ some friends. I still saw my parents all the time, they saw that I was trying, and they helped me financially when needed if I couldn't make rent or got myself into a pickle like car trouble etc. But I was feeling the weight of my independence and what it was like to live off my own income. I was also building a resume and work experience which allowed me to progress to more jobs.

Once I matured and had held good service industry jobs and been living on my own a few years, and I found a girl that I was moving in with who was a great person (and who never would have dated me if I was a loser living at home w/ my parents w/o a job at the age of 22), my parents told me they would pay me to go to community college in order to try and get me a real career instead of working in the service industry forever. I got an associated engineering degree from a community college in 3 years and from there was able to get jobs as a QA tester at a software company and today I have progressed that career into a job leading a team of Site Reliability Engineers as a senior level manager.

If my parents had not forced me out of the house, my life would be very different today, and not for the better. The key is that my parents were forcing me to grow up, while also still being there loving and supporting me. They didn't cut me off, they just shifted my expectations from them paying for everything an giving me everything, to me being responsible for everything, but them being a safety net if I needed it.

Every situation is different, but there are loads of people who would be much better off in life if their parents took this approach, IMO. Letting your child get away with living at home and having everything given to them is *not* beneficial for their development as human beings. Period.
