Well put Vin Diesel.
All you contractor fools who think they are super-clever and on a "great deal", you're gonna get done eventually. The UK revenue are already looking too close for your comfort. Then when you're coughing up all the unpaid taxes, you can reflect on how you managed to not only screw yourself, but also your profession, career and future. Micko's laughing at you. Why not tell him to shove it, maintain your dignity, self-respect and future prospects?
And spare me the sanctimonious "i have no choice" crap. Of course you have a choice, so make a conscious choice to preserve your future.
