Yes, you did. You gave that impression when you said OP was right to point out the list of specific items.
People weren’t disagreeing that small items exist, they were pointing out that worrying about them doesn’t fix very much waste, which is true. So they were also right.
If you aren’t going to come up with true examples, and you aren’t interested in what’s true, what’s broken or how to actually fix the problem, what value is your opinion, right or wrong? If you don’t care what’s true, then why should anyone else care if you’re right about something? And why would I think you’re right when you refuse to bring any actual evidence?
I’m trying to invite you to do more than repeat yourself, and provide some more thoughtful ideas on how to improve government efficiency, and how to evaluate inefficiency. I do work for a company, and my company wastes some money. All companies do. As others pointed out, it’s not possible to avoid some amount of “waste”. This is why it’s important to understand the waste. Without understanding, you have nothing and can’t fix it.
