When the core price of everything used to produce products, and the overheads go up, then the price needs to go up. Or the quantity or quality go down for the same price. Otherwise the business will be losing money and then not able to operate at all.
Some prices just wouldn't be sustainable if they were increased in line with what it costs to deliver the product, and make a profit on it too. Offering less of the product, for the same or an increased price (but not as increased as it would be) especially luxury things that people would then just do without, not buying it at all.
There is undoubtedly some profiteering along the line, and some businesses taking advantage, but ultimately when you're buying a product which now costs more to produce, you're either going to pay more for it, or get less for the same price.
Some would prefer higher prices and the same sizes, personally I think the pp who suggested higher prices but with smaller and cheaper pack sizes would be the best idea - but even then implementing that would cost money that needs to be found from somewhere.
Don't get me wrong it's annoying, but when costs to produce services and goods go up, then that has to be covered somehow.
