This how you grow GDP:

- They sell you junk food for billions.

- If you get chronic disease -> they will forever sell you drugs for billions more.

- If you stop eating that junk, they will still sell you overpriced pseudo-healthy food (all the billion dollar fads)

- And now, even if you just get (a little) obese from all that food -> they got the magic pill ! they will sell you more drugs for $50bn.

Yay GDP is growing! and we should thank them for solving our health problems too!
