The Declaration of Independence follows the idea of life, liberty, and property. Locke determined that all of these points are crucial to natural rights that every human being has the right to no matter gender or race
In the early 1930s, as the nation slid toward the depths of depression, the future of organized labor seemed bleak. In 1933, the number of labor union members was around 3 million, compared to 5 million a decade before. Most union members in 1933 belonged to skilled craft unions, most of which were affiliated with the American Federation of Labor (AFL).
The union movement had failed in the previous 50 years to organize the much larger number of laborers in such mass production industries as steel, textiles, mining, and automobiles. These, rather than the skilled crafts, were to be the major growth industries of the first half of the 20th century.
Although the future of labor unions looked grim in 1933, their fortunes would soon change. The tremendous gains labor unions experienced in the 1930s resulted, in part, from the pro-union stance of the Roosevelt administration and from legislation enacted by Congress during the early New Deal. The National Industrial Recovery Act (1933) provided for collective bargaining. The 1935 National Labor Relations Act (also known as the Wagner Act) required businesses to bargain in good faith with any union supported by the majority of their employees. Meanwhile, the Congress of Industrial Organizations split from the AFL and became much more aggressive in organizing unskilled workers who had not been represented before. Strikes of various kinds became important organizing tools of the CIO.

The quote “... any Indian who received news of the Spaniards could have also easily received the infection” refers to the fact that when the Spanish explorers advanced into Central America, the diseases they were carrying often spread faster than them, including ahead of them.
The context is the so-called Columbian Exchange (after Christopher Columbus), which is the large exchange of animals, food, culture, people, techniques, and diseases that took place between Native Americans (or Indians) and Europeans after 1492.
The quote focuses on one particular aspect of this exchange: the spread of infections. While the Indians did contaminate the Europeans with some of their diseases, like syphilis, many infections destroyed Native American lives because they had not developed a resistance to them like Europeans did. These included measles and smallpox, which were introduced in America through the Caribbean in the early 16th century.
