If natural fruit juices contain large amounts of sugar, why do we only seem to refine sugars from a select few plants (sugarcane, sugar beets) instead of from fruits in general?

I understand that there's differences in the sugar composition (sucrose as a disaccharide vs glucose/fructose as monosaccharides, and that fruits contain more fructose), but I don't understand why "alternative" sugars like HFCS seem to be a relatively new thing, and limited to basically just corn so far as I'm aware.

In theory, humans have had access to fruit pretty much forever, so why do we only use a few dedicated sugar crops to produce refined sugar, instead of more regionally accessible fruits?

 Is it simply a matter of economics, or is there some inherent difference that makes refining fruit sugars impossible?

Cost and consistency. You know exactly what compounds need to be removed from beets or cane every time to produce the same sugar. Strawberries or apples will not yield the same product through the same process (flavours, non-sugar compounds, inconsistent seeds/pulp), and both have (IIRC) lower - and more inconsistent - sugar content than both beets and cane.
