Or more to the point, to compete with strawberries grown in other countries under whatever conditions they deem acceptable.
I've long supported the concept of a VAT-equivalent for pollution (PAT = Pollution Added Tax), where goods are taxed at fixed rates for different pollutants embodied by each manufacturing step, goods leaving the PAT zone are rebated, and goods entering the PAT zone are taxed based on an estimate of their embodied pollution, similar to how VAT works with value changes / rebates / taxes. VAT serves as a way to tax goods without unfairly harming the competitiveness of your products and favoring imported goods, and PAT could extend that logic to pollution controls. But maybe PAT isn't enough. Maybe we also need a HRAT, a "Human Rights Added Tax", which imposes extra fees based on things like human rights abuses, poverty wages, etc embodied in the production of a product, to provide a level playing field for countries with higher standards.
One would have to handle things relatively, of course - a poverty wage in southern California is not the same as a poverty wage in Nigeria, for example, and you don't want to make international sales prohibitive for poor countries simply because their per-capita GDP isn't sufficient. But I'd find it fair to add extra costs at the dock for products produced by factories with inhumane working and living conditions, etc, which keep workers trapped in such conditions by all sorts of means (threats of deportation, threats of violence, unpayable "company store"-type debts, etc). So a strawberry farm in Nigeria paying its workers $2,50 an hour wouldn't be seen as abusive (like one in California would) since that's over double the average national wage and easily meets local cost of living expenses - but a Nigerian farm that left its workers exposed to toxic doses of pesticides and threatened to seize everything their workers own if they try to quit would be seen as abusive even if the nominal salary was $2,50 an hour.
