Yeah you are right. One of the most profitable crops is cherry tomatoes and you can make $1400 per acre on a good year, $900 on average. Saffron, with optimal yields at the most expensive prices per lb, will get you $125k from 2.5 acres.
My dream is to have a farm with enough crops to cover my food & maybe sell a little extra. Out of interest does anyone know a good place in Europe where that's possible for a good price?
