In terms of what can we do - support politicians like Bernie Sanders when they support fighting back against H1B. If you are fortunate enough to choose between working for a company that supports H1B and one that doesn't - go to the one that doesn't. Form a startup if you are in a position to do so. Do anything you can to bring pressure to companies that abuse H1B.
In the end though companies have so much power that to really make a dent, we must pass laws to protect workers in the US.
If we actually care about one another (or more cynically want to avoid the potentially violent unrest that can accompany mass unemployment) we need to do at a minimum make sure everyone is taken care of. I'd say we need to find a way to make everyone feel useful and productive. To do that, we need to rethink how we spend human effort and to what end. If we evolve technologically to the point that jobs aren't about catering the whims of the wealthy or subsistence - why not explore creating an economy of exploration and human evolution? Why not pour our wealth into educating people and increase the number of people who can play a part in helping us live longer, explore the universe, and enjoy life more? Let's replace menial jobs with scientists and artists.
Because left to their own devices, the kings of capital will let the workers replaced by robots starve and rot.
In a March 2011 interview with O'Keefe, NPR journalist Bob Garfield described the ACORN scam: "So let's just recap for a moment the ACORN scenario. You lie to get into – the offices. You lie, subsequently, about the lie you told to get into the offices. You edit the pimp shot into the trailer to create the illusion that you were somehow wearing it during your sting. You go on television wearing the same pimp outfit and let interviewers observe, uncorrected, that that’s what you were wearing when you confronted the ACORN employees. If your journalistic technique is the lie, why should we believe anything you have to say?"
"Yes, it is different in the sense, that there are other ways to commit immigration fraud. But every single person, who sneaks across the border illegally is a fraudster."
You'd be hard pressed to find a lawyer who agrees with that. Now people who break immigration laws to cross the border can utilize fraud once they are here (false documents, stolen identity, etc). But its like saying everyone who breaks into a home steals a TV set. It happens sometimes, it is made easier by breaking in, but they are not the same thing.
More importantly you are side stepping my point and arguing semantics. The article is about fighting people who prey on those so desperate to go to another country they will risk anything. So when you quote someone who (ironically) has committed fraud in several senses of the word and try to change the subject, don't expect much trust for what you're selling.
