The challenge is that the company you work for is almost never the best investment on its own. That's why retirement funds are diversified. I would worry about giving everyone the ability to bet 99% of their wealth on a single company. The reason there are investors is because they've previously invested their money in a risk appropriate way. Now there's a whole argument around intergenerational family wealth which skews everyone's starting point, but it's probably better than concentrating that wealth in a single point of failure (the state who gives you UBI). Probably the right approach to wealth inequality is more tax on non-beneficial uses of money(yachts), and more incentives for mutually beneficial pursuits (cheaper energy).
