That is the way more ethical thing, but it is almost never the best thing from either a financial and certainly not from a health perspective _if_ you exceed a certain income (and the barrier here is pretty low unless you have many kids, which depending on your income distribution you may have to privately insure separately).
If you are self-employed, the public insurance is really nothing more but another (rather unattractive) insurance company you can choose from.
