there selling you the truck and dispatching you?

i recently worked at a moving company in great falls mt that was selling me a truck and dispatching me.whats wrong with this picture? they take there truck payment no matter what. they take out the insurance no matter what. any claims or adjustments valid or not are subtracted no matter what.they leave you with no money to pay your most basic bills (i.e) mortgage or rent power food you get the picture.i do realize the truck payment and insurance etc. must all be payed but shouldn't your dispatch offer you trips that are profitable?I'm just saying there selling you a truck and dispatching you they hold all the leverage.
