The alternative view is that, left to themselves, people don't save enough for retirement and, for better or worse, social security in the US really isn't enough for a comfortable retirement.
That said, there are a lot of reasons why traditional defined benefit pensions aren't a good match for a lot of jobs today. I have one (for a non-union job) but it's mostly a positive because I'm sure I never gave it a second thought early career when I was earning into it.
This is patronizing and broadly not true for a majority of people. This myth was created during the Great Depression to sell Social Security. Some people do not save for their retirement, but vastly most of us do. Should I be forced to pay for those who waste their money on entertainment and high living?
One of the reasons it's broadly not true in the US is that, between social security and medicare, people are provided for at some level upon retirement based in no small part on their own contributions. I paid into both those pools so I'm not sure why you think that money (along with other savings) constitutes being "forced to pay for those who waste their money on entertainment and high living."
