Still Dark Side is speaking through You ;-)
I think it is a favor for USA as well, because USA had HCA in past so we all know, that USA (as Poland), wouldn't get HCA (at least early) ;-) So it's better for USA if nobody has HCA.
For me HCA in WC for other countries isn't problem. We did it with HCA, without HCA, now it will be great adventure to try against HCA ;-)
Mistake was made at beginning - when USA get first HCA in first WC in BB. Then You should complain ;-)
The most fair solution would be if every country would get HCA once, and then HCA should be removed forever. It isn't perfect solution, because perfect solution doesn't exist.
I wrote my statement about HCA few times so there is no reason to repeat this whole discussion.
But I saw few thing in Your post, which should be precised:
- France and China had HCA in past, they made gold and silver (France in U21 competitions). It would make more damages if few countries would have HCA twice, whilst other never had.
- European Championships are harder than World Championships, so they shouldn't be compared.
