One way to encourage those people while also redistributing through taxation would be to reduce or eliminate corporate taxes but increase personal taxes, especially for the wealthy.

There would be lots of knock-on effects from this, such as more company perks to offset the large taxation of salary, but there are ways to combat that (tax benefits provided to employees as compensation). This would allow companies more capital to invest in R&D or expansion. Some of that money would go to higher wages (but if you distribute taxes more heavily to the wealthy along with this, it wouldn't affect median employee salary much).

A downside (among many, I'm sure) would be even more concentration of wealth in companies which might be used for non-free market operations, such as lobbying. It's all interconnected, so it's complex, but it also doesn't feel like we're in such a good situation socially, economically and politically that we should refrain from making large changes like that.
