Current economy vs 1930's economy

I have recently reviewed what I learned in U.S. History about the Great Depression and have found a great resource online. This timeline shows what led up to the depression and how we got out of it. In that era, our boom-and-bust problem was related to the stock market; stocks had inflated prices and then they bottomed out. In this era, the boom-and-bust problem is related to the mortgage prices; they were inflated and then bottomed out in exactly the same way. FDR's New Deal used the Keynesian economic theory that you do not run the government like a business; "the rational thing for business to do in the midst of an economic downturn is to cut costs, but this is the worst thing to do from the point of view of the economy as whole as it further reduces spending, resulting in a further spiral into decline." Instead, he spent tons of money on public works projects and such to get the economy rolling again, gathering much skeptism from the public and much resistance from the conservative supreme court. When he tried to reign in spending in fear of increasing the deficit, the rising economy dropped drastically until he increased spending again. Finally, the economy evened out and the excessive spending ceased. I was at first very upset about the massive amounts of money our current president started spewing out, but after reviewing history, I'm much more content, (although I do NOT believe that money should go to failing corporations). (I also think that entering WWII also played a large part in getting out of that depression.) Another interesting thing is that Sweden, who used the heaviest deficit spending to climb out of the Great Depression, was the first to rise from the ashes. Like most political topics, I cannot broach this subject with anyone who is Republican, so all those republicans reading my blog, you can turn a blind eye to my opinion if you want....
