i think youve missed the point. all teams have agreed to caps but wanted this staggered over the next few years so that they can minimise the immeadiate impact on their teams and amongst other things not have to dismiss hundreds of people..
I very much doubt that, yes its a big drop but im sure many people including drivers will take pay cuts if they keep there jobs, yes people will have to be let go, but the big bosses really wont be giving to much thought to that, bigger companies like toyota, BMW and ferrari could give them jobs else where in the company, and also if you've got "worked for F1 team" on your CV getting a job within the motorsport industry wouldnt be hard at all.
A break away series would take a while to set up and even then it would have to be over seen by the FIA, unless they plan on making there own governing body as well lol
