The obvious thing that is needed is strong labor unions. The open question is why so much of this money is flowing into asset price inflation instead of either consumer inflation or higher wages, or some combination of the two. Even a 50/50 split of consumer inflation and higher wages, which might at first seem to have no benefit, would in fact have the benefit of deflating the relative debt burden that the public is carrying. There is also the very great question of why monetary stimulus was more effective at raising wages in the early and mid 20th Century. Strong labor unions must be part of the answer. The power of the unions forced more of that money to the workers, and less of it to those already holding assets. It is, of course, well known that in every Western country the percent of national income going to capital decreased in the mid 20th Century, whereas the percent of national income going to labor increased in the mid 20th Century.
An alternative, which would not require strong labor unions, would be massive final consumer spending on the part of the government: this is the spending where the government is the final consumer, which is currently only 33% of the Federal budget. A massive program of rebuilding infrastructure would help force the money into the real economy, and this would have some of the same effects as strong labor unions.
