What caused the unintended consequence of "there's no such thing as shovel-ready projects? "

A)  Any of these causes could be a reasonable answer.

Explanation:

When the government needs to spend money on service projects or products, there are many roadblocks in the way.

1. The US House has the "power of the purse," because All Bills for raising Revenue shall originate in the House of Representatives (U.S. Constitution, Art. I, sect. 7)

2. Most State Governments have to approve contracts and vet private industries to complete public works projects.

3. Like all business structures,all of the factors of production need to be in place before work can begin.

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
