I think there is also a brown building tile which gives you an extra worker (and some points). It might not come out until the 2nd half of the game though.You probably had one of the rules wrong.
1. Players start with 2 starting wealth tiles - this should give you plenty of corn and resources for the first couple turns.
2. You do not have to place all your workers at once.
3. You do not have to retrieve all your workers at once.
