Political action has always been the main road to effect change. All the insults and hurling abuse at CASA (perfectly understandable) has probably produced some minor pull backs, but as we can see clearly now, it has not and will never be instrumental in effecting real reforms. The CASA jobs are too cushy, the salaries so high and the path to completely fire-proof itself with ever more extraordinary rules, disregarding any semblance of fairness or economic realities, makes perfect sense. It will continue on this path until a Minister is induced to step in and do his duty.
Therefore political action on the head of power, Parliament, is obviously the main route to take. Unswerving until, as LB states correctly, that actual change is legislated.
