I'm supposed to write a DBQ based around this thesis, but i have trouble figuring out what it means. Can anybody please deconstruct it and explain what it means ASAP? Thank you.

It means that, even though there was an economic boom in the US and many people were making money (especially on the stock market), the fact that many people had more money in their pockets than ever before did not change the social divisions in American society, nor did it change the cultural differences between citizens, nor differences in political outlook.

Even though the economy was prosperous (before the notorious "crash" of the stock market in 1929, when millions of people would lose their life savings and more), and many people had money to spend, America was still socially divided between Black and White, the very rich and the very poor, People born in the US and New Immigrants to this country. There was a disparity (or an inequality) in their status. There was also a vast difference within American culture. Southern American culture had a different set of values and ideal for its future than Northern Americans did, just as the goals of Industrial America differed from those of Agricultural America, or America of the South West or North West. People born in the US had a different culture than those who arrived in the US more recently, and the culture of very wealthy people differed from that of those who lived their entire lives in poverty. Politically, the population of the US was also significantly divided between Republican and Democrat, etc.

In spite of the relative prosperity of the nation's economy, there there were stark social and cultural differences among the population, and the people were still divided along political lines.
