If you play on mobile, you can still hire only Dragon City friends. Simply collect your food/gold from the new Dragon Market on PC.

Has anyone figured out the scaling? I only know the big picture.

You get more food/gold with higher levels. The rewards for each hired friend are cumulative. Each friend you hire gives a slightly higher increase than the previous one. Every 10th friend hired gives a much larger increase in food/gold.
