Maybe not SV, but being an economic migrant who currently works as an independent contractor with a foreign company, I'd want to say that at least in my and my peer experiences, it's far easier to traverse the cast system in an upwardly manner when working in the tech sector than in most other sectors. Of course, knowing people will always be beneficial, as in any situation in life, but for instance in Marketing, you either know someone or have an exceptional portfolio, or you've got the exceptional experience that means that people know you.
