Difference being that there's no desire within either national governments or private broadcasting companies to see shortwave broadcasting survive, while here the FCC wants to keep taking in license fees and private broadcasters without a full-power FM option don't want to go dark, so AM continues to be propped up and will probably still be around in the US long after other nations have abandoned the band.
I suppose the hams will be on shortwave for the foreseeable future, as there are still plenty of licensees here and abroad, but an increasing number of them -- the younger ones, especially -- are more likely to be working VHF or UHF and using digital modes rather than filling the HF bands with SSB and CW rag-chews.
