"You don't just need an infrastructure investment bank, you need a very good idea on what part of your infrastructure you want to upgrade, and what part you basically put on maintain."

"Some are concerned the infrastructure bank could be vulnerable to political interference, as the cabinet can fire the executives at any time."

Therein lies an issue. Would projects be approved on their merit or political ideologies? Would similar projects be approved under a Liberal government as under an Conservative government? If not, then the idea is flawed from the outset!
