If one is optimistic about the private sector driving wealth creation (rather than the government), then one's view is likely that shares will still be higher-yielding on a risk-adjusted basis. Of course, other factors like time horizon and one's personal risk appetite also matter.
If, however, one is not bullish on the long-term wealth creation of American companies (and by extensions the stock market), then the question becomes where would you rather put your money? Personally, I have a hard time seeing better alternatives for the average individual.
