That’s how everyone makes money. They produce a good or service and get paid accordingly.

That is quite a load-bearing use of “accordingly”. You’re allowed your opinions, but don’t make it seem the relationship between work and money is straightforward and neutral. You’re allowed to believe that a streetsweeper or farmer should make less money than Taylor Swift but that is very much not an obvious thing that everyone agrees on.

It’s interesting how you seem to believe your stance is based on science and facts yet you conducted no research to find out what vegans actually eat. Else you’d have found out vegans do typically eat a lot of protein and generally have healthier diets than the general public. The reason being vegans by definition spend time thinking about what to eat and looking stuff up, whereas many people just eat whatever.
