In your opinion, do you believe that the U.S. economy could crash sometime soon (around a hundred years or so) and what do you think will be the reason if it would crash?
The market typically crashes every 8-10 years. One of my favorite sayings is "economists have successfully forecasted the last 10 of 7 recessions." This clever saying is referencing that you can always find at least one economist saying that markets are about to crash. From how I interpret current forecasts (you asked my opinion), I think that so long as the Fed keeps interest rates from going down, we should have an ability to curtail inflation. That said, a lot of investments center around the US government being a safe/reliable borrower, so to have healthy markets in the future, the government needs to get a handle on its spending so that it can afford to pay its receipts with taxes, instead of borrowed dollars. Borrowed dollars only add to the national debt, and create larger interest payments, further increasing the potential that the government could fail to make timely payments, and therefore, lowering its credit worthiness. If the government becomes too unsafe a borrower, lenders would require higher interest to offset that increase in risk, again increasing interest payments - you the see the vicious cycle and how it might start.
