memes

I would counter to say that your aunt is in the minority. If you are talking about hauling individual bags of chicken feed, you are already talking about a much smaller scale than what the meme is poking at. This is more about the industrial scale farms, typically growing corn or soy beans, using combines, harvesters, and other specialized equipment worth millions. This high end equipment has removed all the backbreaking labor you are referencing because that would be time inefficient and cut into profits. When you are plowing, seeding, or harvesting 1000 acres a day there isn't time to haul anything by hand. If you take time to baby a single plant or animal then you are taking time away from caring for the larger field or heard.

Small family farms, like the one you are implying, have old equipment (due to high costs) that embody the hard farmer life, like the open seat tractor. Big farms who spent 400k on their tractor have enclosed cabs with air conditioning and computer controlled auto steering, like the one pictured in the meme.
