Or maybe we could still have debt but on a more limited scale (no credit cards--only secured debt like houses and cars). Yet, I suppose even the limited scale would run into problems such as when housing bubbles pop. Maybe there could be some other rules about counting house prices as risky if the price is significantly greater than the usual price given the income of that area's residents?
Yes (savings could be put into stocks), but with a caveat; things still need to be in balance. The money people save by investing in stocks needs to be in balance with the capital investments that companies make and the amount that others are taking out of the stock market. If the net-inflow to the stock market is faster than actual value that is growing in the system, then prices of stocks will be driven up in bubbles.
With regards to the housing bubble, it was ultimately caused by a high level of irrationality on the sides of buyers and lenders. If the buyers and lenders approached transactions like responsible adults, people wouldn’t borrow more than they could pay back, and lenders wouldn’t issue risky loans. Just a little more sanity and a little less greed would go a long way to help aleviate the risk of bubbles.
