LOL.

Good job refuting my claim with... nothing?

Check the child mortality 300 years ago, you give the wrong number,it's not 80%.

Obviously I'm not quoting a direct statistic here. If you REALLY want me to then I can, but it's a very well known fact that both abuse and mortality was MUCH worse 300 years ago compared to today. The statistics of life expectancy are skewed so far down BECAUSE of infant/child mortality. If you lived to adulthood it was very common to make it into your 60's and even older.

There is no daycare at that era.

Yes, because children were doing hard manual labor when not in school, if they even went to school in the first place. What is better for a child, gaining an education or working your hands to the bone in a rye field?

LOL. We live longer, but not healthier.

That's completely up to the individual. You certainly have the option to eat MUCH more nutritious food in today's society than even 50 years ago. Nobody is forcing anyone to eat McDonalds every day. On average height and weight have increased due to our food being much more nutritious than 300 years ago. This is, again, a fact. The fact that people CHOOSE to eat worse doesn't mean that our food is actually worse, we have the much more variety and nutrition within our food than we had back then.
