Some (true) personal examples: a friend of mine is moderately disabled and lives with his elderly parents. He wants (and they desperately want for him) to be able to live independently in a small apartment so that he can develop coping skills which will serve him when they are no longer around. His parents have the means to help him buy an apartment, but doing so would disqualify him from receiving any disability pension (including free health care).
A colleague of mine once employed a young woman as a secretary/admin assistant. One day her family advised him that they had arranged a marriage for her and as she was no longer living with them she and her new husband would both qualify for unemployment benefits. If my colleague refused to pay her the equivalent of two unemployment benefits (after tax) she would resign. The next week she did.
I used to know a guy who was what I would term chronically unemployable. He had no obvious disability but was seemingly unable to accomplish anything without having his hand held (it was a severe issue, not a joke). As an example, I actually couldn't trust him to fetch a plate from the kitchen. He was unsuited for either technical or menial work because he needed to be instructed down to the barest minutiae. Nice chap otherwise.
He naturally ended up on unemployment benefits and attended fortnightly reporting sessions. He was required to apply for 5 jobs each fortnight which he would be duly rejected from, then report back on his results. I'm convinced that the sheer brutal pointlessness of the process crushed him to the point where he took his own life.
Perhaps a basic income would create other perverse incentives, but it is clear to me that the current system is beyond broken.
