The current "Cost of living crisis", more accurately monetary inflation, has nothing to do with corporate greed, tax breaks, negative gearing or wage increases. 3 years ago inflation was at record low rates and has been for a long time and all of those things existed prior to that. The sole cause of the current inflation spiral is simply federal governments globally (most notably the US) pumping trillions and trillions of dollars into the economy for 'Covid rebates', climate programs, stimulus etc at exactly the same time that global supply chains were broken. Too much available cash in the market chasing scarce commodities equals inflation. its a very simply formula.
Housing affordability also has nothing to do with it. The housing affordability crisis is directly a predictable result of two things. Firstly the ponzi scheme that poses as our current immigration policy which brings in 230,000 new people a year, all needing housing and secondly the insanely liberal foreign investment policies.
People whine and howl about buzzwords and peripheral things when in truth the problems are more simple but bigger and the real problem is both sides of parliament support these issues.
