My pleasure to bounce this one around, Itheblaze, I enjoy thinking on these things. For some of the things you mentioned though, it would depend on how much control you had and the limitations of the time travel. Would anybody get married if they could look ahead 10 years and see that they got divorced or their partner was going to die in an accident or get a crippling disease? Would you start a business if you looked ahead and saw it fail with you bankrupt?
The insurance business would be finished overnight. Because if you know you are NOT going to die early or have ill health why would you bother having cover?
Betting shops , all kinds of betting on chance would cease too.
If only backwards time travel is possible you could find out if people had lied to you in the past?
