"The only reason high fructose corn syrup is cheaper than sugar in America is because of corn subsidies."
BZZZT! It started with Nixon because of sugar price supports, beet and cane! And there's still massive intervention in that market, I'd assume the economics are still similar. Thus Super-Mega-MAGA RonV42 ✝️ (npub1yev…9nx0) is not to the point, the market is only a factor after this.
Remember that HFCS is a little plus or minus the sucrose 50/50 composition of glucose and fructose. Also remember that crop price supports play a role in ensuring people don't starve due to a bad harvest, or here limiting the swings of meat prices and availability.
"Then we'd finally be free of all of that ethanol in our gas."
That I don't see happening, but ending that insane "burn food for fuel" policy (minus distillers grains for animal feed, corn to ethanol leaves behind the protein) would be a very good thing.
TD;DR: sugar is the bad thing in excess, the source doesn't matter much if any.
