Same in the UK, even highly populated areas (e.g. surrounding London). Trains are very expensive compared to cars. There are discount schemes for some groups (e.g. student/pensioner), but it's really for the wealthy only.
That sounds like a deliberate policy choice? Trains have became more expensive here during Covid, but back when I was using them extensively, a national annual subscription (lump sum, after which the rides were free) only cost a little more than double what insurance+plates alone cost for my car.
