But not really accurate either as Meat prices vary from country to country due to other factors besides rates of pay.
I think using the staples like Milk and Bread is far more accurate and linking them to the min wage.
Out of interest What is your price their and min wage?
Also everything has to be taken into account. Like the cost for heath insurance, super annuation,paid leave per year, sick days,fuel,electricity, water..its a big equation trying to compare apples with peaches. I think Norway or some country around their has the highest tax's but the happiest people....
