Italy government was choosing who to build the bridge (maybe the one in the previous joke).
3 contractors made bids, a German, an US, and a Brazillian one.
The German bid that for 40 million he could make a near indestructible steel bridge with perfect tolerances.
The US company tried to do the opposite, they offered to make a cheap concrete bridge, with "just enough" within the requirements of the law, for 10 million.
The Brazillian then, offered to make the best concrete bridge ever, for 30 million, 10 for the US company, 10 for the Italian politician, and 10 for themselves, and as a bonus they would help the Italian politician to convince the population that the US-made bridge was better than the German one.
