Fitness depends on what area you live in.
In my area we have a lot of active outdoor people. So, you can see many fit folk wherever you go. Alas, they are still in a minority. My doctor told me last year that he used to see 1 or 2 morbidly obese people a week when he started his practice nearly 30 years ago. Now he sees 1 or 2 a day.
I think one of the issues is that while the overweight segment of the population may not have increased in numbers as much as we think it has, those in that group are on the average significantly heavier than similar people 20 years ago. This is a thought on my part, not a documented fact. I have no evidence other than my own empirical observations to back it up.
Note: I am very sympathetic to the plight of the overweight. They live in a world where there is too much questionable food that makes us gain weight combined with terrible nutritional policies/advice of our government and certain 'public service' organizations for over 30 years. They are supposed to summon up the willpower to resist their native body chemistry for the rest of their lives - a ridiculous idea. I was well on my way there, trying and failing many times to lose 20-30 pounds and more importantly stop the yearly weight gain that had me adding 1/2 to 1 inch to my waistline every year. Thankfully, I listened to Dr. Lustig's Sugar, the Bitter Truth video which got me going in the right direction.
