This is a poor understanding of the concept. The idea behind a Basic Income Guarantee is that it is received equally by every citizen in the country. It's an idea linked to Negative Income Tax and other like proposals, and shares support of many with a more libertarian/economically conservative bent.

In most areas of North America where Basic Income experiments have occurred, the overall workforce does decline, but in very specific ways: mainly with single mothers and teenagers. Mothers choosing to stay at home with their children, and teenagers graduating high school are more positive impacts on the society at large than the greater retention of wealth by the highly motivated.

Wealth can only be created in societies, and therefore the overall health of a society should be of paramount concern to those interested in creating wealth. While I do not advocate for many socialist principles, a certain baseline ensures the society remains sustainable in the long term, thus allowing its members to grow wealth.

Both too much (Communism, socialist Europe) and too little (Argentina, Venezuala, the US) will lead to inevitable social collapse and the reduction of wealth (or the ability to create more) for all.

You do not live in a self created bubble.
