I'm in favour of maximum ratios of total compensation. Stock values, dividends, salary are all added together to get a total compensation value.
Start it at something like 50-1, then gradually lower it as the actual workforce is allowed to control an increased share of the company.
There is still incentive for growth; the growth is simply distributed more equitably.

Good news. I hope Canada gets there, but I doubt we will. We are too focused on oil expansion and infrastructure to pay any mind to the 'dirty poors' right now.
If we had kept Petro Canada as a crown corporation past the 1980s, we could be funding UBI NOW, but of course, conservatives fucked that up.
