What industries do you regard as being highly competitive? Can you identify any barriers to entry in those industries?

Solution

The Fast Food Restaurant industry is very competitive in the US.

Barriers to entry;
1) The biggest is obviously the government in the form of local and state health boards, food inspectors, and nationally the FDA.
2) Start up cost: (a) buying everything you need, (b) getting through the initial months that will inevitably slow while you gain a reputation.
