Based on all the positivity in these comments, it does seem like the UK has at least a more laid back, sort of entry-level culture making hiring decisions than the US does at the moment... awesome ;)
More jobs? No. But 'more' doesn't really matter. It's hard enough to move to the US.
It's easier for him to find a tech job in the UK (there are plenty) than it is to move to the US and get a tech job (for which he'd need to get sponsored by a company).
The biggest difference between US and UK tech isn't job 'quantity', it's job 'quality' (the culture in the US is better imo). But I'm not sure that's OP's priority currently.
