I dunno, I've seen society go from "vegans might get some fries but will likely go hungry from a restaurant" to "every restaurant except one has at least one vegan option permanently on menu". During this time stores and restaurants have stopped supplying eggs from cages birds, and fur farms has shut down across the country, and schools has started serving meat-free Mondays, multiple types of meat alteratives can be found in every corner store rather than specialist shops, the EU has banned animal testing for cosmetics, pet abandonment has become criminalised, etc...

None of those things would have happened if people weren't going vegan, asking for vegan options at restaurants and stores, and pushing for vegan ideals at stores, restaurants, local councils and government.

The meat and dairy lobby is massive, intense and wealthy. I understand that it may seem impossible to work against such an opponent. But the force enacted by each individual going vegan is what has made these changes seem worth it to all the above institutions, in the face of such massive industries, and that makes each individuals force incredible.

Systemic changes are slow, but when you see them across decades they are undeniable.
