Nonsense,
In government spending, it's all public money - every dollar has to be accounted for and it does this in the budget each year. The idea that the government could secretly be spending billions or trillions of dollars and nobody would notice, is just silly - they have a lot of money, but it all has to be accounted for - you can't just hide that amount of money.
It also creates another problem, if you're spending billions of dollars on a secret "exotic technology" involving flying saucers, that implies that thousands and thousands of the worlds cleverest people, universities and tech companies would be working on it (for obvious reasons)... Next you're going to tell me in this day and age - that nobody would talk, nobody would sell their story, or leak a video of it working - every single person's lips remains sealed?
Government officials can't even have an affair, or commit basic tax fraud without it being in the news the next day, how the heck do you expect them to be able to contain this sort of thing?
The US government spent $81.1bn on black projects in 2019, so yes every dollar is accounted for, it's as if you don't think the military has secret projects like, is this a joke post? You realise they developed loads of projects involving thousands of people in total secrecy? it's kind of what they do
