No point getting angry any more.
If you're youngish, capable, skilled and don't have any obligations, leave.
Why would you stay and help pay into the pension pot of people who voted to steal your future? Fuck them, let them suffer.
It's the only way people learn. Stop thinking you can stick around and help, you're only limiting your own opportunities.
The country doesn't deserve your skills or what you being to the table. Leave. It seems scary, but it's really not. Just do it and leave behind those who fucked up to fix their own mess.
For those who voted remain and can't leave. I'm sorry, it sucks you're left trying to help those who fucked up fix things and continue to subsidise those who fucked up.
