Not necessarily.
"Apple (AAPL), Microsoft (MSFT), Alphabet (GOOGL), Cisco Systems (CSCO) and Oracle (ORCL) are sitting on $504 billion, or 30%, of the $1.7 trillion in cash and cash equivalents held by U.S. non-financial companies in 2015, according to an analysis released Friday by ratings agency Moody's Investors Service. That's even more cash concentration than in previous years, as these five companies held 27% of cash in 2014 and 25% in 2013. Apple alone is holding more cash and investments than eight of the 10 entire industry sectors." [1]
Also, the top 1 percent owns 90 percent of wealth in the US [2].
"First, economic inequality has worsened significantly in the United States and some other countries. The richest 1 percent in the United States now own more wealth than the bottom 90 percent. Oxfam estimates that the richest 85 people in the world own as much wealth as the bottom half of humanity.
The situation might be tolerable if a rising tide were lifting all boats. But it’s lifting mostly the yachts. In 2010, 93 percent of the additional income created in America went to the top 1 percent."
> As a practical matter, consumption taxes can be made progressive by combining them with a low-income tax credit or a universal basic income.
I agree that a consumption tax can be combined with other policy to prevent the regressive nature of a consumption tax alone. This requires wealth be taxed in various forms (ownership of investments, land, etc).
