How did the overprinting of currency lead to the Roaring Twenties and the Stock Marcet Crash?

Not too simple.

Explanation:

Printing money makes the dollar worth less, as the more dollars the less each one means in physical gold. So, the more money printed the less the amount meant, meaning that inflation went through the roof. As inflation rises, people take out loans and what-not that will never be repaid. Thus, the banks fell apart with no real value in the depreciated dollar and the economy collapsed under it.

Lots of things have changed

Explanation:

I am essential worker, therefore I am not staying home because I can't. My children however, are home and they are missing school and all that entails. I went to the grocery store today and they had no meat, bread, tp, etc. So yes that part was hard. We have stocked our pantry and if everything closed we would be ok for up to 3 weeks. I miss family size meats and being able to go into the store carefree. I miss seeing people in my small town on Main Street its those small businesses that are being hit so hard.
