Global Entry/PreCheck/Clear are pretty benign. The only information Global Entry requires that the government won't already have from tax records, DMV records, border records, etc for most citizens are fingerprints. I don't see it as much different than a drivers license/passport requiring a picture (for most people that's going to be the only way the government gets a picture of them on file).
