The middle class was different after the industrial revolution than it was before because prior to the Industrial Revolution, Europe had a small middle class. Following the Industrial Revolution, the middle class greatly grew.
After the industrial revolution, the lower classes were been able to "rise up" economically by getting new jobs in factories, thus much of the lower class entered the middle class.

There could be several options for answering that question. I'd say one area of strength for the Articles of Confederation was that they encouraged coordinated, cooperative action between the states to resolve any disputes between the states. Another strength might be the establishment of a Department of the Treasury and Department of Postal Service so that money could be coined and mail service provided.
Meanwhile, there were also weaknesses, such as each state got only one vote, regardless of the size of the state. Also, each state could tax trade from other states -- there was no authority in the Confederation to regulate interstate commerce.
Answer:
If President Lincoln hadn't been assassinated, I believe that Reconstruction and the post-war era would have been more historically positive and ambitious. I think Lincoln would have achieved more things politically and socially for America, and would have done more to fight against many injustices in this country. Andrew Johnson did not have a positive presidency, says his impeachment. Lincoln had plans, but Andrew Johnson created policies and actions that went against the Republican Party and angered many, like his pardoning of Southerners. Lincoln would have continued to be a great figure for his party and I believe would have provided more as leadership than Johnson. If he was not assassinated, I believe that Lincoln would have continued his legacy and his fight for justice in America.
