Milk in Switzerland can be as low as 1.5CHF (1.6€) per liter when you buy 10L at once at discount. But it use to be 1CHF then, 1.2CHF for a single litre at full price (and at the time 1CHF was 0.60-0.70€), so people were already mad of the increase. However what is not always known, is that milk is heavily subsidize by the governement because it's not profitable to produce it in Switzerland to be able to sell it at this price, so we all pay the difference in taxes.

But for sure in other countries with lower income, fruit, vegetable, cereal, milk, can be much more difficult to buy. It all depends on priorities of the governement when taxing and giving subside.

yikes!
