You mean like how the USA include thousands of dollars of fake rent in GDP numbers for every single homeowner in America under the justification that if they didn't own their homes they'd be paying rent? Like that kind of politicization of economic metrics publications? Or maybe you mean how the USA only counts someone as unemployed if they are pursuing their unemployment insurance but also every state has a financial incentive to deny as many unemployment claims as possible? Or maybe it's the constant debate around whether to use a consume price index that excludes things food and rent?
