Several reasons apply, with Purchasing Power Parity (PPP) providing the best overall explanation. It’s often popularly known as the Big Mac Index or why the same burger can cost $8, $5, or $3 in three different cities. It’s based on a basket of goods, like a gallon of milk, a loaf of bread, etc. We’ll cut to the chase with the biggest line item.
The average monthly rent in Israel is in the area of 4,000 NIS (US$1170). Needless to say, you can find something significantly lower or far more upscale. If you’re curious, according to Zumper, today, the average monthly rent in San Francisco is $2,195. But, to compare further, the average rent throughout most of Ukraine is around $300.
When you take out the rent as one of the major line items in the cost of living, $870 per month or nearly $10,500 per year is removed from the equation – attributable primarily to PPP. There’s more to it than that, of course. It’s appropriate to remember that at one time, everything in Ukraine (apartments and houses) were state-owned. When Ukraine broke away from the Soviet Union, nearly all property became owned by the citizens of Ukraine. That’s a story for another day, perhaps.
Leastwise, the PPP issue carries across many different goods. A gallon of milk in Israel is indexed at $6.60, but in Ukraine the same gallon of milk is just $3.34. Internet Service? That seems to run around $27 per month in Israel but less than $10 in Odessa, Ukraine. The PPP variation is not a constant, just an aggregate.
