Products which require a lot of manual effort to harvest are generally luxury goods, not essential for feeding the population. If for whatever reason it seems that this year there's not going to be enough migrant labor to harvest your strawberries, then when the spring comes you can plow that field over and plant potatoes, which will require much, much less labor and feed more people from the same field. This year is very much not 'business as usual' both in production and also in consumption. Just as most other fields, farming needs to adapt to the changing situation; IMHO it's counterproductive to invest a lot of resources to try and preserve the status quo - we're going to see that some farm products become harder to grow, or harder to transport, or are more difficult for people to afford because of economic problems. It does not mean that we should heroically strive to preserve our ability eat as before, if that means that we're going to be eating less of product like that - less fresh food year round (greenhouses or imported), less meat, less fruit, etc, than that should be accepted, and it's okay; and it's okay if the circumstances force the farmers to switch from high-value labor intensive foods back to cheap, efficient staple crops. A prime example is the scenes I've seen from Netherlands sizeable flower plantations; as flower purchasing in most of their export markets is way down, a lot of the harvest is just discarded. I'm certain that some of that field/greenhouse capacity will be repurposed for basic food growing instead.
