In your case, probably yes. Seriously, though: if you fly only once every other year, and PreCheck saves you 10 minutes, then the 30 cumulative minutes you save (assuming 10 minutes saved per trip) is probably not worth the $85 or $100 you'd spend. If you fly 2-3 times a year, then it starts to become worth it (2.5 total hours saved over five years for $100 = $25/hour). If you fly a ton, then it's really worth it.
But if you're going to be snotty over a comment, then you probably don't care to do the math, and you probably view frequent flier status as some horrible insult to equality, so there's nothing outside of blind agreement with the original poster's premise that'll satisfy you.
