Have you ever tried to produce food, though. It is surely not free, and I refer you to the labour theory of value (LTV) for a straightforward explanation of that.
There is not enough wild growing food to feed the entire human population. You are welcome to live in the woods and survive on only berries and mushrooms go right ahead.
Agriculture is hard work. Hard work has value and therefore the resulting product of agriculture (food) has value and is not free.
I am not some capitalist pig, I generally agree with anti-work sentiment and am pro work reform. I am working class, working to live, if i dont work I'll be homeless in 2 months. But also I realise that if you build an extremist ideology based upon blatant falsehoods like that in the posted image, it is doomed to fail.
As someone with an acre farm that produces far more than I can eat, agriculture isn't hard work, and I'm doing the hardest version of it. Actual large farms are mostly automated and require less work than any cashier job.
Have you seen wages? Have you seen the price of these things? That just isn't true. I can easily get several pounds of berries in an hour in the right season but minimum wage might get me 6 oz of that same in season berry.
Berry net and black berries, a single swipe and jiggle gets you 4-6 oz. I don't know what you mean by processing, washing never takes long and removing stems isn't that important unless you mass making jam or giving them to toddlers that can't remove them on their own.
