So, sneakers double in price and my salary will increase sharply?

No, sneakers increase sharply. Double/double is for comparison purposes.

Does my employer have to boost my salary to stay competitive with sneaker makers?

Not on purpose. It just works that way with internal production and trade. It can't work that way when production and trade occurs internationally because oppressive regimes force their people to work at a repressive wage.

Why?

Because if they did people couldn't buy them.

So, salaries double, prices double, how is that not 100% inflation?

If wages stay consistent with prices, there is no underbuying and no overbuying. "Money" does not have a divine value set by God.

I suppose you have a real world example where a country stops imports and their economy doesn't sink?

If wages stay consistent with prices, there is no underbuying and no overbuying.

How do wages stay consistent with prices?
