It is worldwide, not just America. The Concrete Club had four of the five families involved in it. Gambino and Genovese families were and are the biggest influences in the construction business. Any building costing 1 million or more, the bidders had add an additional 2% in their overhead that was kicked up to the mafia families. Today the families still have influences in construction, despite the government trying to kick them out. They might get kicked out of carpentry and framing, but they could control the electrician and plumbers for example, which means they still have their fingers in a major project going on. Dont be surprised if you see some mobster owning construction companies, or services. Many times they use that as a money laundering business, in they will work on their families and friends houses or property at no cost to them, but write up a bill of sell using unclean money to turn it into clean money so the IRS will not hound them so much.
