There's little doubt that the market is kept afloat by money printing. There're a couple of issues, however, in the medium term:
1. As you print more money to keep the bubble growing, it takes more money printing to sustain. 2. As you continue to accelerate money printing, the fundamentals start to turn from bad to worse.
While the media have successfully kept the public's attention on the large monopolies that have benefitted from lockdowns, the crumbling of the working class does not bid well even for those monopolies. In essence, it's exactly what Karl Marx predicted: the monopolies are so successful that they're killing off their customer base.
In the long term, this type of money printing can have only one end. It has always happened in history.
The chart now shows a tendency to cover the gap at 28500. Although they'll very likely inject another trillion to keep it going a bit longer at that point.
