I’ve been seen this talking point being repeated by anarchists and liberals. One guy recommended me this book which it stated that:

"The Soviet Institute of the Economy estimates that as much as 3 percent of industrial production and from 5 to 25 percent of raw material output is falsified."

Is this true? How to debunk this talking point? I’ve been questioning myself too much about this, PLEASE HELP ME I DON’T WANT TO BE A LIBERAL
