I'm in great health, and young, so I'm not worried about saving for retirement (yet). But starting a company is still really damned hard. It's years of hard work, too much time at the office, too much time away from friends and family. Too much fear that tomorrow no customers will show up, or they'll go to your competitors or you'll find our your DB backups don't work and you have to go out of business. It's fear that you're not managing employees correctly, or not hiring the right people, or not prioritizing the right things.
The government can't make any of those things go away. And the only issue it could help is money, which has terrible downsides to go along with it.
