But either way I don't really see what greater point you're trying to make.
You seemed to disagree, and be trying to make a distinction where no practical difference can be found. You also seem to agree that they haven't been held accountable, which makes this apparent distinction even less coherent! This kind of just comes across as contrarian, or perhaps sophistry to avoid agreeing with an apparent opponent?
Does that imply unaccountable, or does it mean Congress thought they were doing a good job?
The misinformation era means there's a gulf of frequently incorrect assumptions about what the Federal agencies actually do.
I mean, what if Congress created them to be unaccountable? Then both things would be true!
these are very different situations, and it appears you wish to defend the motte and get the bailey for free?
I never said all government organizations are unaccountable? Just that (practically-speaking) some organizations are unaccountable because they rarely (or never) are called to account by those who are supposed to hold them accountable. This could be due to them simply being a low-stakes organization that demands very little attention, for all I know!
Interesting that you call out a specific fallacy whilst bringing your own strawman into play!
The mechanism is there. If Congress is not passing new legislation to change their actions, that de facto means that Congress is content with the current actions. They have been accountable to Congress, and Congress has been content to let them keep doing what they're doing.
It's equally plausible that the reason Congress has not called an organization to account is simply because that organization is beneath Congress' notice. Congress has as incredibly broad mandate, and necessarily prioritizes. This means some organizations are simply not enough of a priority to warrant any attention.
It is in this dearth of attention that waste can thrive!
If Congress hasn't been doing its job, then they don't just seem unaccountable, they actually are.
