Only if you're taking it literally. This doesn't have to be a power plant, but a bus service that will take their kids to school every day, a teacher that will teach these kids in a classroom, which is much cheaper than private tutoring, street lamps, pavements, emergency services...

The solution is a crypto based economy that involves consensus spending, with smarter people individually having an edge to insert occasional checks and balances, rather than gangs of power crazy bureaucrats running amok.
The trillions wasted on nonsense could easily be diverted or redirected to science and space programs that would solve a lot of problems at once. The price would be shifted to mass casualties that would be involved in a space program. A better path.
