Not at these premium levels... Who can afford a plan with a $3k deductible? I'd guess $7k is closer to the average that most people buy.
There's also the question of what is "catastrophic". Costs are through the roof, especially with most providers tacking on anything they can think of (whether it be from greed / gaming the system, or defensive medicine.)
The plan we were offered by BCBS of Alabama had a monthly premium of $1167.00. Our deductible was either $8k or $12K - for a family of three. I think I figured that I was looking at an out of pocket cost of around $23K per year. Who can afford that? Certainly not a self employed small business owner who makes less than 100K a year. And that was the first year - I have no idea what the second year would have cost us. We went with Medicare - $500 a month with a $3K deductible.
