Background information: flora tristan was a women's rights advocate from france. she wrote this excerpt in her journal about life in manchester. unless you have visited the manufacturing towns and seen the workers of manchester, you cannot appreciate the physical and moral degradation of this class of the population. most workers lack clothing, bed, furniture, fuel wholesome food–even potatoes! they spend from twelve to fourteen hours each day shut up in low-ceilinged rooms where with every breath of foul air they absorb fibers of cotton, wool or flax, or particles of copper, lead or iron. they live suspended between an insufficiency of food and an excess of strong drink; they are all wizened, sickly and emaciated, their bodies thin and frail, their limbs feeble, their complexions pale, their eyes dead. if you visit a factory, it is easy to see that the comfort and welfare of the workers have never entered the builder's head. god! can progress be bought only at the cost of men's lives? what is the main idea of this passage?

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
