not sure that made in the US is the issue, but you may be right about CRC “beating” them to OE overstock. I lived and worked in the US in the mid 90’s and spent a lot of time buying and selling bikes and bits to build up dream rides cheaply. Supergo (now defunct after being bought out by Performance Bicycle, a national chain) led the world in snapping up OE over-stock from (largely CA based but not build) manufacturers, I remember buying $600 RRP forks for $199, old XT or XTR (8spd when 9spd had just come out) for less than 1/3 of RRP etc.
As Hora says CC has always been a high-end full-rrp type retailer hence the article continually mentioning IBDs (independent bicycle dealers) as suffering at the hand of CRC/Wiggle, not all the US-based discount mail order specialists.
The US has always been a perverse mix of capitalism and protective/socialist financial policies. Pay caps in some sports, spending caps controlled by claiming rules in motorsports, and a long history of protectionist taxes and penalties to protect local industry (worked in steel/aluminium sectors) against foreign competition.
