i think they just picked up some freakish top earner who put in 7 days @ 12 hours a day..
i doubt the avg bloke can pull in that amount bending over or arching upwards to grab the low hanging fruit..
the undocumented fellow probably ropes in $1000 - $1300/week at best
if these guys pulls $4000/week to pick sacks of potatoes for the farmer to sell to major supermkts - ya reckon they have enough profit to pay them high wages...? your dreamin
