Since the foundation of America, the idea of an unmarked 'frontier' always captivated the minds and hearts of people. People had this idea of freedom where they could always resettle away from the cities and migrate to the frontier to start a new life.
Whenever the frontier opened up, thousands of people found new fertile land and started a new life.
Unlike in European cities where poverty and crime would create deadly protests, the US would just keep on expanding to the west and provide more for the people.
With the end of the Frontier, there was no new land nothing for rural person to look forward to.
However, the problems of poverty and social cohesion could easily be solved by providing good education and better jobs to people.
The US had to move on from an agriculture society to an industrial one and eventually develop an economic system that provides for all and pulls people towards cities and not sparsely populated rural areas.
The correct answer is: "labor laws and anti trust cases".
Both are elements which limit the actions of corporations when they pursue their own interest of profit maximization without caring about the negative consequences that their economic activity may be causing to other economic agents or to the society as a whole.
On the first hand, labor laws defined the terms that should govern a labor contract and the rights of employers and employees, so that any abuses can be commited on any side.
Secondy, anti trust regulations (like Sherman Antitrust Act) and cases enable to prevent the consolidation of monopolies, which have serious negative consequences for consumers: high prices, lower amounts of production (possible shortages) and lower quality products, and also for society, as monopolists who control an industry do not have incentives for investing on innovation or efficient tecniques.
Since most of the colonists came from England and since England controlled the colonies, events in England affected the colonies' development.
As an example, let us look at the English civil wars that involved the Puritans, Parliament, and those who backed royal rule. These lasted for about two decades in the mid-1600s. During the time that the civil wars were actually going on, there was very little development of colonies. The English were too busy with the wars to be able to pay much attention or put many resources towards colonization. After the wars ended, however, colonization resumed and the colony of Carolina, for example, was created.
