The history of food in these places is very long compared to other places. There was a time when the only way to preserve meat was to salt-cure it or smoke it. And nothing was ever wasted, most people were poor. That's why sausages, especially, along with other cured and smoked cuts, became so prevalent.
Those traditions have continued. People eat what they have always eaten, they stay with what they know. I'm sure more fresh beef and pork cuts are available to buy today than there ever was in the past, but it hasn't caught on there to an extent that it's replacing traditional fare.
The US, on the other hand...the colonists brought with them to America their ways of doing things, and you can find ethnic foods anywhere. But the fresh beef steak and roast, and pork, and chicken - those became uniquely American as westward expansion - and learning from the native peoples - led to a whole new way of producing and eating meat.
