US healthcare is clearly a huge barrier to older employees joining startups.

At my company we have a great selection of healthcare that's fairly affordable both for employees and the company. I think it's as good or better than any packages I've seen from big brand-name enterprises. However, as a European founder, I was shocked by the complexity and effort that went into the comparison shopping necessary to get anything other than expensive, poor coverage. The quality of what's out there from JustWorks, Gusto, Zenefits et al was frankly shocking - and they are feted as "making it all easy and affordable". (We use Trinet which although in many ways antediluvian has very, very good health options at least for NY).
