LTCG rate on a $10M exit is already 20% today (and I think even 23.8% if the Obamacare 3.8% surtax applies, which I’ve not researched recently, but I think does apply).
There’s a heavy twin push to find more sources of revenue and to increase taxes on cap gains specifically, so I don’t know that I’d bank on capital gains taxes continuing to stay low long enough to take advantage of them. All taxes on $10M exits are going up; cap gains probably faster than income.
