Where do you get your "information"?
Currently, in an urban area of NY state where I am, a basic family plan is ~$1600 and an individual plan is ~$550.
You may say "what about the deductible", but it looks to me like the deductible is effectively only a payment plan. Even if you have a chronic condition, and you know you will go through the deductible for sure, you don't gain anything by paying for a lower deductible. The deductible is nowhere near the difference between $1600 and $4000 anyway.
Of course, pricing will vary by zip code because healthcare providers cost different amounts in different places, so a rural area might be more expensive where there are fewer doctors who have more negotiating power versus in urban areas where there are more doctors competing.
