The trouble in law is to get qualified (in the UK). If you can't finish the 5 years of study or you can't find an internship at the end (extremely competitive), you've wasted your entire time and money and you will never be able to give legal advice and charge £500 an hour.

But after that it's a walk in the park.

The competitiveness of lawyer and developer jobs is really not comparable. All companies have a legal department and hire lawyers, internal lawyer is a good office job with a decent pay but nothing extraordinary.

There's no comparable career path for developers because only tech companies hire developers, the comparison is unemployment if you couldn't make it to a tech company.
