I think these sentences are wrong. Some people say it in this way, but I think they are not correct. They say: ...I mean, the thing is, in spain is a lot of classicm, people are classes, they were classes.
I check classsicm on internet, and I did'nt find such a word.
As to be the useage of classes, it's grammatically wrong.It should be: people are classed, people were classed.
