Of course. But that is NOT the same as making a profit on each person which
was what you originally stated.

A casino does NOT make a profit on every customer. On average they do.
If the casino miscalculates or has a card counter at blackjack are you
claiming that they then made a loss on every customer? Of course not.

If my wording was wrong, that's one thing. But the laws of probability
are mathematical facts - even if dice and cards can be rigged.

The point is, though, if the casino _were_ to miscalculate, and operate
a craps game at odds that were mistaken - so that players, on average,
won on each bet rather than lost - then it would become the most popular
table in the casino, and, unless action were taken, the casino would go

Nope. Look at the TV show "make a deal". The proper way to play is to stick
if the deal is less than the average of the prizes on the board and to
accept the deal if it is greater. People do not play that way.
Ie, people in general play so that dutch book bets win.

In the case of a casino, there may well be enough people who know how to
play, but in the case of the casino, they simply bann people who make use
of the arguments in that way. You have a certain probability of winning at
Black Jack ( assuming you play long enough) if you follow the right
strategy. If you do, they will ban you.

quoting me:
Otherwise, people with worse health risks will purchase insurance in
disproportionate numbers - changing the average rate of claims - and so
premiums will have to go up. When they go up, people with better health
risks become less likely to purchase insurance, so premiums go up again.

Yes, opening the market for someone to come in and offer insurance which a
broad spectrum of people will buy.

Insurance companies are not entities which I worry about (when was the last
one to go out of business?)

Individual health insurance is *dead* in the United States. Insurance
companies are moving on to concentrate on the other kinds of insurance
they sell. The market is wide open.

Nobody's walking in.

(Unsafe drivers is a complete non-sequiter. Or are you claiming that all
people who might become unhealthy are unsafe drivers?)

Well, here in Alberta, people with cars over 10 years old can't get
insurance from insurance companies, they have to get it from a special
pool that the Alberta government established for people considered bad

cars over 10 years old? What has that to do with anything?

Nothing wrong with that - but, unfortunately, people with drunk driving
convictions could also get auto insurance from that pool. I think they
may have fixed that now, though.

Auto insurance is weird, and it differs considerably from health
