I can hope for all the positives here, including many that cherry mentioned, and 3%-4% growth sounds great. The ability to increase the deficit with higher government spending can get that much growth or more, as it did with Reagan. But I suspect that the deficit will increase dramatically based primarily on tax cuts on the 1%.
Tariffs will increase those Walmart prices, but also help domestic manufacturing a bit (and/or increase imports from non-Chinese countries unless we put a tariff on everything - and I anticipate there will be intrusive new government regulation determining exactly which imported content is Chinese, and do things made in China and then shipped to us with a different label from Vietnam actually count as Chinese). Rising inflation and pressure on entitlements will counter some of the deficit pressure, at a cost of having people on social security and other forms of government assistance be more stressed.
I expect that there will be tangible, actual evidence of the crimes that Hillary Clinton was accused of but never proven, but that evidence will about Donald Trump and members of his Administration. I believe that President Trump will unintentionally reveal classified information (and significant information, not something like a Snowden news article). I believe that there will be a number of financial/graft indictments/convictions similar to under Reagan (or US Grant if you want to go that far back). And I believe that no one who expressed concern about Hillary Clinton with regard to classified information or corruption will spend 1/100th the amount of time an energy on those topics when they occur in a Trump Administration. But at this point, it doesn't matter - the positions were just tactics, and they worked. My worries start at bigger risks than debating points. The biggest risk, and I believe that this is a very small but finite possibility, is that President Trump loses control for about 30 minutes during a tense crisis and 100 million people are killed in a nuclear exchange. Very unlikely, but the impact is very high.
The second major risk is the effect on the world climate regime when the US pulls out. More heat means a more rapid transition faster, which leads to more conflict around the world.
The third major risk is a major economic crisis like 2008; not only will a Trump Administration not have a sense of how to handle it, but we still haven't fully recovered from the last one. And in the aftermath of an economic slowdown, to deflect blame from the Trump Administration, I believe there is a strong risk that Trump will find some other target to demonize (he really was doing a protocols of the elders of zion thing with the last set of his ads).
Oddly enough, many of what people would consider to be my personal financial interests will be helped by a Trump election. I'll probably save $20,000 per year in taxes, and after 1 day of Trump the stock price for the aerospace company I work for has gone up by $20.
Deficit spending will go up to just shy of $1T per year (fraudulently justified because of the "Obama deficits" that Obama inherited from Bush), and with a limited fraction of that being additional government spending
