Why is free trade good? Isn't competition easily attacked via subsidation, for example, if trade is unregulated (why Chinese cars are not bought in EU)?
That's a broad question, and I don’t have time to give a full answer right now — but I recommend checking out some classic talks by economist Milton Friedman on YouTube. He explains tariffs and subsidies really well. For example: https://www.youtube.com/watch?v=Tcw3Z3vMqWw
