Not they are not.
Oh good it is the fear mongering pro-illegal lie that if do not allow illegal immigration then the price of goods will skyrocket.

You might assume that the plentiful supply of low-wage illegal workers would translate into significantly lower prices for the goods and services they produce. In fact, their impact on consumer prices — call it the "illegal-worker discount" — is surprisingly small.
The bag of Washington state apples you bought last weekend? Probably a few cents cheaper than it otherwise would have been, economists estimate. That steak dinner at a downtown restaurant? Maybe a buck off. Your new house in Subdivision Estates? Hard to say, but perhaps a few thousand dollars less expensive.
The underlying reason, economists say, is that for most goods the labor — whether legal or illegal, native- or foreign-born — represents only a sliver of the retail price.
Consider those apples — Washington's signature contribution to the American food basket.
At a local QFC, Red Delicious apples go for about 99 cents a pound. Of that, only about 7 cents represents the cost of labor, said Tom Schotzko, a recently retired extension economist at Washington State University. The rest represents the grower's other expenses, warehousing and shipping fees, and the retailer's markup.
And that's for one of the most labor-intensive crops in the state: It takes 150 to 190 hours of labor to grow and harvest an acre of apples, Schotzko said, compared to four hours for an acre of potatoes and 1 ½ hours for an acre of wheat.
The labor-intensive nature of many crops is a key reason agriculture continues to rely on illegal workers. A report by Jeffrey Passel, a demographer at the Pew Hispanic Center who has long studied immigration trends, estimates that 247,000 illegal immigrants were employed as "miscellaneous agricultural workers" last year — only 3.4 percent of the nation's 7.2 million illegal workers, according to Pew statistics, but 29 percent of all workers in that job category.
