How about, instead of creating a for-profit industry that will gradually canibalize the public funded healthcare options, until they've become the only option and start squeezing everything for more money, we invest in the public system so it can address the issues we currently have?
Suggesting private healthcare to address a public healthcare issue is akin to fixing flaking paint by burning the house down. Instead of, you know, investing into some paint and fixing it.
I've posted some challenges myself and will occasionally take a stab at guessing one of the entries, but I don't get around to engaging every day or even week. For me personally, I think the game is very fun, but the number of challenges per day/week is too high. If you scaled back a bit, I think you'd get more participation on each individual challenge.
