Yes, I think it's a bit sad that parents wouldn't want to support their children to follow whatever their dreams are, or at least to help them have time to explore those interests. But would gladly spend money on big ticket holidays.
It's not about uni or no uni, but the reality is that going to uni is potentially prohibitively expensive for many. It's probably the most expensive form of training or education someone could undertake, but it would be no different if parents refused to support their children in any other pursuit: vocational training, work experience, travel and volunteering, setting up a small business, etc. if they could afford it. I know someone who trained as a professional stunt person for film/tv (which if you don't know anything about it, is an incredibly challenging training programme that takes years and years), and his parents supported him as much as they could. I know others who did a year of travel mixed with working/volunteering on farms and in forestry because they had an interest in conservation. Their parents supported them as much as they could. Support, obviously, doesn't mean 'pay for it all' though. It means exactly like it sounds, offering help where possible to make it easier. That could be financial (money or housing), it could be practical, it could be logistical (offering a ride to public transport/college/uni/work), etc.
Yes, I can't see why if you could, you wouldn't, because we should all want what's best for our kids. That said, you never know the family dynamics at play. Unfortunately, no matter what we 'should' want, not everyone does want what's best for their kids. In some families, there is a lot of jealousy and resentment and manipulation. It wouldn't surprise me at all if these sorts of parents did not support their dc, unless it was for show or personal benefit. I'd hope they would be the exception rather than the rule.
