a bit of a steep generalisation tbh.
Totally publicly funded infrastructure projects tend to be mismanaged and routinely go over budget but in any case even now in the UK under the conservative government there are a ton of publicly and privately funded infrastructure projects in development, major include HS2 and Heathrow runway expansion (Which Corbyn is against because of enviromental concerns ).
Interesting that you use the term “fairly” too. That’s a term that isn’t necessarily conceptually certain. What is fair? I believe in equality of opportunity not equality of outcome.
Where are these ‘shattered communities’ too? Are you talking about the UK or the West
