Ayeeen bayyeeen shaayyeeen again.
The specific question was about cost estimate. Is it in the range of $1 billion or $5 billion or $15 billion.
Once you know the cost, then the next thing is, Who is going to pay for that $hite. And that my friend is some international bank who is ready to assume the risk.
You don’t walk over with a bagful of your coins and say “Buddy I wOODD Lake to Build the fing paplane.”
Then the money is secured form an international bank.
Then only then one can talk about jobs and such.
Do not put cart in front of the sickly horse.
