The only valid way of reducing levies is to cut out waste and inefficiences and to renogotiate unfair contracts inherited from previous ECs or the developers.
Reducing services and neglecting current and future repairs and maintenance to cut levies is ripping off people who have bought into strata blocks expecting a cerain level of service and amenity.
This is going to become a big issue in the future as people on fixed or reducing incomes watch their levies rise (as they will with inflation). The answer is not to start cutting services and facilities to suit the lowest common demoninator. Those who can't afford to live in some buildings need to find somewhre they can afford.
This obsession with reducing levies is turning some perfectly decent buildings into the crumbling slums of the future. Every time you reduce levies by reducing services, neglecting repairs or starving the sinking fund, you reduce the value of everyone's homes.
