It might still happen, but there's a high chance that it will come to light sooner rather than later. Whistle-blowers don't have to fear the same repercussions as in autocratic states.
Its amazing that you parot that nonsence while Assange rots in prison and Snowden is hiding for a full decade.
Those that fire "whataboutism cannon" arguments etc. are equally bad. Nobody is honest (or rational) here, lets not pretend otherwise, even little kids understand better. It is what it is, its human nature I guess. I don't have a solution, except that you have to accept and adapt to that sort of game, nothing more or less, especially not thinking you have some sort of moral higher ground.
US Inflation data is famously understated, and the number of methodology changes we've had in the last year should alarm everyone. We actually saw disinflation in healthcare insurance costs at one point last year, after one particularly criminal adjustment in the calculation by the BLS caused the lowest negative print in decades.
The EIA reports since Biden have also been a disaster, to the point where they are "vowing" to work on the accuracy[1]. I highlight this one in particular because of Biden's catastrophic mishandling of the Saudis and the de-facto war on oil his administration is leading.

Maybe. Its hard to be sure when autocratic countries lie about their economic data.
edit: for those two with their "everybody lies and are awful" argument (one of the oldest and most beloved Russian tactics whataboutism). You will properly not get it if you don't already understand it - but issues with accuracy has nothing to with doctoring all your numbers to keep the gravy train going. Transparent liberal countries can have issues too, but compared to authoritarian ones the issues a trivial.
