These systems lasted for more than 10,000 years and were only abolished when they were no longer useful for selfish interests. For thousands of years, power was held by landowners (local bosses, kings, the aristocracy, and the high clergy), who required the forced labor of serfs or slaves to cultivate their lands at minimum cost to maintain their privileged lifestyles. When some European serfs emigrated to other continents (especially the Americas) and became landowners themselves, they typically applied the same system of subjugation through servitude or slavery to indigenous populations and Black people brought from Africa whenever it was most cost-effective.
Although the liberal ideas of the Enlightenment gradually turned broader sectors of society against slavery and servitude, it was not until the late 18th and the second half of the 19th century that slavery and servitude were abolished in many countries. Why? For two reasons. First, it was not until then that power shifted to the bourgeoisie (limited suffrage) or to adult males who were neither women nor slaves (universal male suffrage). For the majority of the new sovereigns—the bourgeoisie and the common people—these two institutions of subjugation and exploitation were either harmful or of no benefit. The second reason is that it was not until that era that less labor was needed, thanks to the Industrial Revolution and improvements in agricultural techniques.
In other words, they did not abolish this great injustice until it was no longer convenient for their selfish interests.
Please, let us not repeat that mistake with animal subjugation and exploitation. An increasing number of people are against causing suffering to non-human animals, but for most people, personal interest and the well-being of their loved ones remain the priority, even at the cost of harming others. Let us not wait until it is more convenient to buy in vitro meat than traditional meat for the mistreatment of animals in factory farms to end. Let us also consider the interests of the victims.
Let us not be driven primarily by our own selfish convenience, but above all by our sense of justice.
In fact, it is better not to wait for the consumption of cultivated meat to be approved in your country, as you can already eat very healthily with vegan options.
