Let's say we had no illegals picking blueberries ~ the product would not disappear. The price would undoubtedly go up for a while, but suddenly Oregon berry growers would have competition in the Midwest ~ just like the good old days.
That and mechanization would bring the price down, encourage more berry growers to plant more berries, and we'd all have more and cheaper berries and no illegals.
Same with tomatos ~ except they've gotta' breed the taste back in (now that they know why tomatos lost their taste) ~
Doubtful. I was at the market today and had to laugh my @$$ off when I saw an 8oz pack of okra priced at $4.99.
That's the price of no transient labor, no neighborhood kids working for some spending money, onerous regulations, and mechanization.
