Why Australia are you so dam expensive?

Clothes, cars, rent, food! Everything is so expensive here! And why?? I wanna buy a pair of jeans but i have t spend $100 and it'll be made cheap in china. I wanna go shopping, I'l get milk and bread and it'll come too near $10, rent! Don't even get me started, why is the rent so high!?? There is so much dam room in Australia, there is sooo much room in Australia, I could get a decent flat in Tokoyo and it would be cheaper! I'll go to a cafe and spend $5 freeking dollars on a coffee, and it'll be form the crabbiest, rudest service, yes australia has no idea when it comes to hospitality. And what the hell is it with chicken sandwhiches in OZ?? Do you not know what chicken is, 'No i didn't order chicken s h i t, I want chicken. You can quite easily go to Europe or U.S and but food and clothing half the price and it'll be good quality!!
