The fundamental problem with trade of that sort is what do the customers pay with? Finding something rich high tech places have that third world places want a lot isn't difficult, it's finding something with an equal value density goes the other way that's hard. If the colonies don't have something equally valuable to send home in the same number of ships, they don't have the money to buy infrastructure heavy imports with.
