Do you realise how unbelievably patronising you sound?
If the analysis hasn't been made (and I have no reason to believe you on that) then how are you in a position to judge either?
We all have opinions on govt expenditure and the best use of it. I would suggest that using all the funding on getting between two cities quicker is not the best use of that, and greater investment in connecting people to and within their own and neighbouring cities would produce better economic and social incomes.
The approach you suggest is what has led to more investment in the southeast in recent decades as it produces better economic outcomes..on paper at least.
