I agree with you on that. We had almost a decade of QE since the last financial crisis and ZIRP policy for about 7 or 8 years after. Europe, Japan, and other parts of the world went NIRP and I think there's something like $15-17T worth of negative yielding govt bonds out there last time I checked. And look what happened last year at this time when the Fed tried to "normalize" rates. They couldn't. Now the S&P is at record highs and expecting another Fed rate cut in a week or two. We never got close to normalizing rates. I could go on and on...but long term, this isn't good.
As far as the pro-growth policies, at least Trump is not advocating implementing China-first policies as many of the Dem candidates are currently doing about breaking up the banks and tech firms. The only entity that benefits from those policies would be China. Unlike Bernie, he's also not talking about killing health care companies like UNH, CVS, and ANTM...and whether you like it or not, he's not out to kill fossil fuels. I'm serious that if we woke up tomorrow and the future of the Dem party, AOC, suddenly became president for the next 4 years, the market would not open. If it did, it would be down at least 40% within a week or two. So by "pro-growth", I guess I could have rephrased that as not intent on destroying major sectors of the market.
I also agree that the corporate tax cuts are probably only temporary. Removing them would be priority #1 if Warren gets into office. So then whatever the markets gained due to that would simply be reversed...except for lost revenue of course.
I've heard the dollar is strong simply due to supply and demand. There's a strong demand for dollars around the world. I think it's also due to the fact that US treasuries are the best safe yield around. So that alone creates a need for dollars. There's more to it than that and I need to read up on it. I also thought QE would lead to inflation around 2009 / 2010, but surprisingly it did not. I suspect that the reason it did not is the same reason why many don't seem very concerned about government debt. I suspect it's one of those things that doesn't matter until it does. As long as not too many people panic, everything will be fine.
