Neds Newt (1997)

Rusty McCabe is well-known around town as a snobby rich boy, but when Ned's photos get mixed up with Rusty's at the photo booth, Ned finds out that Rusty's family is broke. At first, intending to disgrace him, Linda instead convinces him to be sympathetic, and people start donating things to Rusty's family. They later find out that these photos were from a theme park called "Live Like Ordinary People Land", where rich people pretend to be poor.
