Your post makes very little sense. For a start, where did I say that 'all' home students were the same as 'all' international students? That's illogical. I was merely stating my observations.
Students that stay home, are by definition not 'international' students'. Furthermore, if you had actually read and understood my post properly. The reason for people being so 'focused' is because they want to work in the UK. They might not not necessarily know what they want to do, they just want a sponsored job. Fulfilment, 'passion' etc is just not a consideration.
Bear in mind that very few fields , and within them, companies, sponsor visas. Even for supposed 'shortage professions'. I'm in tech, have very valuable, niche skills. But still couldn't move jobs. Because companies don't want to sponsor visas. The moment I got permanent residency the offers flooded in. If even I found it difficult, imagine a new graduate that has very little to offer. Much, much harder.
Now, obviously, all of this doesn't apply to people staying in their home countries, where they already have the right to work.
Also, I sense that you think I'm making a value judgement on which attitude is better. I'm not. Just pointing out that when a group has limited opportunity it makes sense for them to grab hold of it with both hands.
Home students will always have more opportunity. They're not restricted to grad schemes with a few companies for a start. Direct entry jobs with large firms, all the other firms that don't sponsor visas, working your way up from an unrelated job, there's plenty. There's nothing wrong with taking the time to decide, but that's a personal choice. The idea that international students compete on the same basis as locals isn't correct.
