if there were no exploitable workers, who would clean the toilets?

Hawaii has a long history of recruiting foreign workers to do the hard work and the dirty work:
First Japanese, then Chinese, Filipino, Korean, Portuguese, etc.
As soon as one group established itself and found or created work away from the hot, sweaty can fields, they did so.

Here are some practices from days past:
* legally bound by 3- to 5-year contracts
* Japanese, Chinese, and Filipino laborers paid at different rates for the same work
* whippings, for such offenses as talking, smoking, or pausing to stretch in the fields
* Plantation owners often pitted one nationality against the other in labor disputes

And now, it's the Hispanic workers.
