You have to be careful about “slave labor” even on goods labeled “made in USA”. The Northern Marianas Islands have had some pretty bad sweatshop situations. That’s a US Territory and it products manufactured there can be labeled “made in the USA”. But employers there have held employees as indentured slaves while they work off their rent – even forcing abortions so that workers could stay productive. (google marianas sweatshop for more details.) This is a situation that elected officials from both parties kept hushed up.
From an environomental perspective – it makes sense to buy local – not just the same country, but the same region. The impact of shipping goods from distant locations is something to consider. (If you care about that stuff. Not everyone does.)
I will say – as a parent trying to find toys that aren’t made in China is HARD.
