If your economy is entirely dependent on a doomed industry, maybe, instead of artificially keeping it alive, focus on modernising that economy instead?
Just HN things: the meat industry that serves 75% of the world population and will continue to do so for the foreseeable future is "doomed".
Factory farming is an ecological and ethical dumpster fire. Animals take up a ton of land, feed, and water, and they're pretty terrible at turning feed into meat. The grain that livestock eats can feed more people than the meat from those animals.
Factory farming is expensive and unsustainable at our current population, and it's only going to get worse as time goes on.
Once the industry around lab grown meat starts to scale, the price will fall to the point that it's no longer economically viable to farm animals at scale. The lab grown meat will be cheaper, have the same or better nutritional content, and do it with a fraction of the land, water, energy, and feedstock input.
Given equivalent mass of organic matter as input, lab processes will likely output many times more edible protein. You have the extra benefits of not needing to wait years for an animal to grow up, you don't need to maintain acres of farm or clean up after the animals. You don't have to butcher the animal and deal with the waste products.
On the scale of a generation or three, factory farming is absolutely doomed. An unsustainable process can't compete with a sustainable one that operates at a fraction of the cost while producing many times more output.
Note that we're specifically talking about industrial factory farming. Small farms will likely always exist, and you can buy "real" meat as a luxury item at an appropriately high price.
