OP, some of us have no choice as we need to live for now, so just can't afford it? It's quite rude to infer that we are stupid when we don't all have the money to pay into a pension?
I worked in the same job for 20 years, I was only able to join the pension scheme when I reached manager level, and then 2 years later I went on ML and went back part time, so barely anything was paid into it. I went self employed to be able to be around for my child more.
I was going to start paying into it again but then XH left me and our 4yo. So I then had to build up my part time self employed work, to a full time business. I had to remortgage my home for 25 years to be able to keep it, so I will be repaying that until my SRP starts.
As I am self employed now, there is no employer to pay into my pension. XH had no pension to speak of and I was happy for him to keep what little he did have, as I was keeping my house. The pittance of maintenance that he pays, and the lack of regular contact with his child, means that I have 98% of the childcare and the costs to deal with on my own.
I had to make decisions in order to live and survive now, and not worry about the future. My house is my pension, if I need to I will sell it, downsize, or rent and live off the proceeds. My main concern is to keep a roof over our heads now. Any spare money I have is paid off the mortgage, not that there is much with a school age child to bring up.
That doesn't make me stupid or foolish. But sure, feel free to carry on insulting anyone who is not as fortunate as you.
