LG and Kenmore Refrigerators; Why Do You Want to BUY American?

LG and Kenmore Refrigerators, what do they have in common? LG make some of Kenmore refrigerator.  The differences, are small.  I found that Kenmore frigs tend to be priced higher than LG, but the once a while "big discount" bring it back inline with LG pricing.

What's the lesson about all of this?  Why buy American brand, when it is made oversea anyway, the store/distributor-Sears make the same money. If the both products are being equal, why do I have to wait for Kenmore to be marked down in price when I can get the LG anyday?
