Yes, the things that hurt the 50% below the median the worst. I can stomach my utilities bill going from 200 to 800 eur, I won't like it but we'll manage.
The other half of the country will revolt, probably.
The 10% includes food and energy items, but also things that people won't be spending money on when the price of food an energy goes up so it underestimates the impact of an increase in the price of food and energy.
I'm not in the EU, but this is what our family has done. Our food bill alone has gone from around 30% of our takehome pay to around 40%, and we just don't have the income to absorb that increase.
So the useless crap, the things that make inflation look not so bad, gets cut out.
I'm in the US and this is what I hear from the people I know.
Most of those people don't carefully track their expenses so they just know that they have less left over after paying for the necessities. A couple of them do track expenses carefully and when I was talking to them a few months ago they said that their personal inflation rates were at least 20% over the previous 12 months. I just checked heating fuel costs and they're up 36% from last year, which is less than I expected given what other people have said about their costs but it's still significant. It's definitely going to be a hard winter for a lot of people I know.
When things like used cars were driving numbers people absolutely wanted to include those in the messaging. I saw zero inflation-bugs complaining that really we should be using food and energy only when those weren't the dominant forces.
But these people are largely hired and paid for by the government. The government, who has to pay extra if inflation goes up (esp. in Europe). Obviously they have a preference for lower inflation.
(and frankly, to a small extent their argument is valid. If everyone switches from Coca-Cola to Pepsi, even if they do so because it's cheaper, then Coca-Cola has no place anymore in an inflation index. Prices are meant to affect buying behaviour and products must be allowed to replace each other)
