The works of the roots of the vines, of the trees, must be destroyed to keep up the price, and this is the saddest, bitterest thing of all. Carloads of oranges dumped on the ground. The people came for miles to take the fruit, but this could not be. How would they buy oranges at twenty cents a dozen if they could drive out and pick them up? And men with hoses squirt kerosene on the oranges, and they are angry at the crime, angry at the people who have come to take the fruit. A million people hungry, needing the fruit- and kerosene sprayed over the golden mountains. And the smell of rot fills the country. Burn coffee for fuel in the ships. Burn corn to keep warm, it makes a hot fire. Dump potatoes in the rivers and place guards along the banks to keep the hungry people from fishing them out. Slaughter the pigs and bury them, and let the putrescence drip down into the earth.
There is a crime here that goes beyond denunciation. There is a sorrow here that weeping cannot symbolize. There is a failure here that topples all our success. The fertile earth, the straight tree rows, the sturdy trunks, and the ripe fruit. And children dying of pellagra must die because a profit cannot be taken from an orange. And coroners must fill in the certificate- died of malnutrition- because the food must rot, must be forced to rot. The people come with nets to fish for potatoes in the river, and the guards hold them back; they come in rattling cars to get the dumped oranges, but the kerosene is sprayed. And they stand still and watch the potatoes float by, listen to the screaming pigs being killed in a ditch and covered with quick-lime, watch the mountains of oranges slop down to a putrefying ooze; and in the eyes of the people there is the failure; and in the eyes of the hungry there is a growing wrath. In the souls of the people the grapes of wrath are filling and growing heavy, growing heavy for the vintage.
Overpopulation is a myth, and we only can't feed and house the existing population because of capitalism, not because of lack of resources, exactly as the meme you're responding to points out.
We are using far more resources as are regenerated. This is why the Earth overshoot Day is a thing. We are at almost 2x the resource usage that would be sustainable.
When you satisfy the needs of your population, have cheap birth control and good sexual education (which was given in almost all socialist countries) people will naturally have fewer children. In poor countries people have the most children.
Under capitalism, people in many rich countries are panicking because fewer and fewer working people have to feed more and more elderly, even though we have the resources to easily meet their needs. But profits have to keep rising, so the shrinking working population has to be more and more productive. The superexploited growing populations in the global south are what keeps this system alive, so overpopulation is even encouraged under capitalism.
These are hardly good examples of communism, just like how modern day U.S. is a pretty poor example of capitalism. A capitalistic society shouldn't prop up failing businesses using money taken from the workers. A failing business should just fail, yet they've been "rescued" time and time again, at the detriment of the people who don't see those funds and keep being exploited for their labour.
True communism hasn't ever been implemented, and I wouldn't look to dictators as examples for how to do it. Dictatorships are incompatible with the fundamental ideas behind communism.
