The CPI isn't a made up number. It's an average of prices of goods. The government doesn't manipulate prices of goods, at least not directly. Sure, the economy might be gamed by the government and large corporations in general, but the Consumer Price Index isn't (and can't really be) directly manipulated, without changing its definition (what is included in the index).
Most of government is comprised of bureaucrats who do their jobs through many administrations. This take shows a complete misunderstanding of government work.
