Imo, if you ran the country and had to put up with the likes of Dezz & Alex on a daily basis, I think the salary & pension is deserved.
Imagine if after your term you would have to go job hunting amongst all the labour/liberal/greens business owners & recruiters.
You would forever be labelled.
Not to mention what strings a business could pull if they had an ex-mp on their books. Hookups/loopholes for days.
I wouldn't want an ex-mp using his knowledge to give an unfair advantage to a company/industry, good or bad...
