They wanted more political and economical power. During the 18th and 19th centuries in Spanish America, Creoles would lead the fight for Latin American Independence due to the fear of social unrest
Well they both helped to modernize/industrialize the U.S, so it depends which view point you would like to take. They stole the plans from england, who had successfully monopolized industrialization for almost a century, who would be upset at this loss of control and therefore business. However an American would probably be thankful for the industry that blossomed as a result of these actions.
There were several factors that moved America towards independence from Britain. They are as followed:
1) The development of an American culture- Even though the colonists were still part of Great Britain during the 18th century, many of these individuals were natives of the colonies and had never even been to Great Britain before. This is a huge transformation from when settlers came here originally to find freedom from religious persecution during the early 16th and17th centuries.
2) Colonists being forced to into wars they did not want to fight in- The British army was constantly fighting with other European powers like France in North America. This resulted in colonists being part of wars they did not want to be in (like the French and Indian War).
