There is a seasonal / migrant worker visa for this reason. For instance, near me, Kiawah Island's resorts are partly staffed with Jamaican guest workers because the seasonal nature of the job. In high school I worked as a bagger at a grocery store on another island that was incredibly seasonal, so we had Russian guest workers during the summers.
Some jobs probably just wouldn't get done without either A) a wage increase or B) guest workers, e.g. particularly brutal agricultural tasks. We can allow the necessary workforce in for these tasks if need be.

The poor.
Having grown up in an area with a large Hispanic influx, they did. I currently live in an area with little to no Hispanics, but we do have a lot of poor African-Americans. They do the jobs I grew up seeing Central and South Americans work.
The problem with the illegal influx from southern nations, is they can also crowd out native blue collar markets by working for less, and are willing to live an impoverished standard of living. We should not be forsaking our own countrymen so we can get cheap lawn care from a wage-slave underclass living in third-world conditions on American soil.
The poor here just aren't willing to do that work at that price. The supermarkets aren't willing to pay more for the produce. Something has to give and in both countries I'm sure it's going to be the rules on visas.
Let's frame this a different way...
"Who will actually spend the money to develop a strawberry picking machine when there are piles of people that are willing to do it for below minimum wage and no health care?"
Having some group you use at near slave labor status can hold back technological innovation.
All you're doing by continuing the exploitation is keeping such automation from being developed, as you rob it of it's market.
It is so predictable that the whole "but what about the farmers" is touted as a reason to flaunt immigration laws. The farmers are not owed such a subsidy by the American people. They will adapt if they are forced to. They would be stupid to do so before they are forced to.
Sure, and who cares about the people who can't afford food in the meantime while we wait for the new Eli Whitney? You are proposing fixing one problem by creating numerous more problems.
You also shouldn't treat poor people as a single group. Yes, some poor people will be receiving these higher wages but no all. There are still people lost in the transition just like there would be people lost in the transition waiting for innovation from Eli Whitney.
1859: But who will pick cotton? Perform household chores?
We will either develop a technological solution or gasp the wages and benefits for picking strawberries will rise to such a point that it makes sense to pick that up as a career choice.
Who will pick strawberries? Who will clean your hotel room? Etc.
