What he means to say is that because you are a farmer you are a member of the capital holding classes rather than the lumpen proletariat.

Most programmers are of the capital holding class too. At very least they will own a computer, which is all the capital you need for 99% of what programmers do. There are exceptions, but there are also exceptions in farming.
The capital holding class isn't anyone who holds capital. It's anyone whose main function in society is based on holding capital. Think of a landlord.
