It shouldn’t matter where it’s produced as long as proper/adequate quality control is managed during the manufacturing process. China has significantly cheaper labor and the technical expertise that makes manufacturing there attractive to cut costs to stay competitive.
Buying domestically only to support local businesses seems like a good idea, but we now live in a global economy. Parts are sourced from many non-domestic sources. Generally, it makes no business sense to pay more for a part than us necessary. Businesses are for profit so cutting costs directly helps. However, there are exceptions- some businesses may want the tighter control of manufacturing locally, and they can afford to do so because the market will pay the increased costs.
And realistically, I doubt buying domestic only will have a much of a financial impact since the majority doesn’t follow this thinking.
