Therefore methods already considered were: -  big reforms at the beginning of a legislature,  -  small steps over the whole legislature,  -  reforms agreed to be enacted only in subsequent legislatures,  -  reforms on a trial base,  -  opt ins with sweeteners,  6  BIS Review 16/2008  -  reforms by stealth etc….
There seems to be no miracle remedy. At the opposite end even parties which explicitly campaigned on a “no need to reform” platform or pensioners’ parties have also not succeeded.
