Re: More tax revenue?
"Really, where's that? I've been in security as a perm for ~15 years and I can only think of one contractor I've worked alongside in that time (over five employers)"
These days I tend to work for large multi-national suppliers who have large multi-national clients (think companies > 10000 employees).
The team I'm currently working with is about 15 strong now (up from 1 about 3 years ago :) ) and only 3 of them are permie. The supplier just can't seem to find enough good people for these consultancy gigs who are permanent workers. To be honest they struggle to get decent contractors as well - especially on the account I work on - it isn't an easy customer :)
They asked me if I would be interested in a permie role about 2 years ago, and when I expressed my starting price I didn't hear anything back. However, they did keep me on for another two years on my day rate (which has gone up several times due to all the extra value I bring). Based on what I originally asked for they would have made an absolute packet out of the client had they taken me on as a permie back then.
"Perhaps this is why I can't afford to run a car when everyone else in infosec seems to be rolling in money... :S"
Too many variables to comment on that, I have no idea what kind of area you work in and for what type of clients, but if I told you that the technical aspect of my job, whilst still challenging on occasion, is only about 25% of what I actually do it might give you some idea of where to focus. If you would class yourself as a 'techie' then you're missing out on a huge market that wants people with a broad range of people/admin/management skills on top of being technical. That's when the rates start to shift up a gear or two.
I might be expensive, but I'm good *value*. ;)
