H-2A is expensive and prone to abuse. It is generally considered a failure by both employers and workers who participate in it. So I’m guessing your use of fantastic and generous is either sarcasm or uninformed?
I've read opinions from farmers who say they wouldn't be able to operate without H-2A.
The stipulations are incredibly generous with unlimited renewals though have to leave the country for 60 days every 3 years.
There's also a pathway to citizenship for specializations in agriculture such as the dairy industry. And they can bring family members too. It's an uncapped program too.
At least on paper it's an incredibly generous visa compared to other types of visas with more restrictions for family sponsorship and immigration.
I agree it's expensive though, that's a big reason why there so many illegal immigrant farm workers. A few reforms and that can be legalized through H-2A
