free market = small or no government intervention in a market place, allowing the market to make the best decisions for everyone.
The idea is that markets are super efficient in a way a government isn’t and will automatically make the best decisions.
An example being something like:
If we don’t have a minimum wage a business can pay what they want, but if they don’t pay a good wage then nobody will take up the job so a business needs to pay a good wage and the market has just regulated itself because nobody out there will work for a low wage…
Sorry this is a bad and verrrry basic explanation I’m still in bed.
