The French Monarch in the earlier times had no problem spending money and they also made a lot of spending because they got this money by taxing the people of France and they also taxed the nobles who had a lot of money.
This harsh taxation which was also unfair and inefficient in structure by the monarchs resulted in the crisis in France and ultimately led to the french revolution.
These taxes were also raised at a very high rates making lives of people of France very tough.
Slaves had to work like freemen but freemen weren't owned. freemen when they worked they got money for their job and slaves didn't get paid at all. i don't know what example you want me to use
