The two main arguments I see criticizing veganism is that it's expensive/not accessible to the poor and it's still vulnerable to the evils of capitalism. Which are fair arguments.
You go to a vegan cafe compared to a non-vegan cafe and 9/10 times the vegan cafe is gonna be more expensive. However, I actually stopped eating meat initially to save money, and so that eating healthy on the road was easier. If you think cooking your own vegan food is more expensive than a meat meal, I think you are just misinformed and/or a bad shopper. Not to any fault of your own. I think what the vegan movement needs more than preaching is education. People don't realize how cheap, healthy, and easy being vegan can be. It is a dramatic lifestyle shift, sure, but completely attainable by most, assuming a normal meat diet is already attainable for you ofc. You don't have to stop eating meat cold turkey either. I think that's actually a terrible way to do it. If you have any kind of interest in veganism, just dip your toes in the water. Go to a vegan cafe first and try some dank ass food so you know what's possible. After that, try cooking some simple vegan meals. Hell, just eating some oatmeal/granola with fruit is a great start and example for how cheap, easy, and delicious this shit can be. If you like it, try implementing it into your daily diet day by day while still eating meat. Then maybe switch to vegetarianism for a while once you're comfortable before going vegan. Ease it into your life.
And, yes, agriculture labor is exploitative. But if you're buying unethical, exploitative meat, you really can't use that as an argument against veganism. Buy local and ethical. Local and ethical meat is pretty expensive, but fruits n veggies really aren't all that expensive local. Often, you'll find that it's cheaper to buy the local and ethical shit. Next time you're on highway 1 or some place with lots of agriculture, stop by those lil farms, or look for signs selling shit. I know you can get local and ethical avocados on highway 1 for like 25 cents. Buy an avocado in whole foods or some shit and you're gonna pay like $2. Not to mention how much better for the environment veganism is. If we're gonna agree that both veganism and meat boy life are exploitative capitalist swine systems, then that argument goes out the window and you then gotta compare the other aspects. Veganism wins most of those other arguments.
Is veganism the perfect solution? Fuck no. Is it a better lifestyle/diet choice than meat life for fighting capitalism and saving the earth? Yes.
