Bitcoin and Robinhood will end badly for those who can least afford it

Millions in precarious jobs are betting scant savings on worthless stocks and cryptocurrencies via share-dealing apps

The US economy's K-shaped recovery is under way. Those with stable full-time jobs, benefits, and a financial cushion are faring well as stock markets climb to new highs. Those who are unemployed or partially employed in low-value-added blue-collar and service jobs - the new precariat" - are saddled with debt, have little financial wealth, and face diminishing economic prospects.

These trends indicate a growing disconnect between Wall Street and Main Street. The new stock market highs mean nothing to most people. The bottom 50% of the wealth distribution holds just 0.7% of total equity market assets, whereas the top 10% commands 87.2%, and the top 1% holds 51.8%. The 50 richest people have as much wealth as the 165 million people at the bottom.
