yes it is basically slave labor - and its the root of the problem. The right doesn't want to stop the illegals because they see it as potentially hurting business and the left doesnt want to stop them because they see them as potential political supporters.
We the people need to willing to pay the higher price of goods and services that would be required to be able to have these employers pay a fair and legal wage to entice Americans to do these jobs and then we need to put business out of business that continue to hire people not allowed to legally work in this country - We cant have it both ways, we cant demand low prices for produce and at the same time expect the farmers to hire Americans for a fair wage - - it just wont work
If we really want illegal immigration to stop we need to go after the employers who hire them, and make programs where the needed people can come in legally to work and then go home when they are done - - and we also need to accept the higher prices this will cause
if the jobs are not here then the reason most come will not exist - and then ICE can focus on the remaining who are coming for other reasons and stopping them will be easier
