As the other commenter said, even if your claim about having more free time is true (I highly doubt it, more likely we simply aren't counting the various tasks historical peoples had to do which were still "work", but not their main job, and overcounting the "work" that modern people do when they are actually just scrolling tiktok), as a society we spend far less time making food than we used to. This is obvious by the fact that in the past century, worldwide levels of famine and hunger have dropped lower than they have ever been in recorded history.
