So you want to write spagetti in another language because webdev is getting too difficult? In my opinion one should strive to learn their craft well, and if you havent by now, you should very quickly educate yourself out of writing bad code. Otherwise it's a habit that keeps you feeling bad about you and your code and hold you at disadvantage against that competition you are so worried about.

But if you think a break in another domain would just magically make everything better, try becoming an expert in some obscure domain in some not-well reputed company. There most of your work will probably end up be muttering a few words in meetings and drinking coffee, with no one to tell you what to do as they dont really understand your domain.

There are a lot of codebases with really bad code that no one wants to take care of, so findind a gig like that would probably also pay you well.
