The United States last hosted a World Cup in 1994, and 32 years later, SoFi Stadium delivered the kind of opening ceremony that only Los Angeles can produce: a Southern California native performing to 70,000 people, Hollywood royalty in the stands, and the host nation three goals up by halftime. Ticket holders paid up to $1,900 each for the privilege. Some of them still did not know where they were sitting when the gates opened.
