The inspectors are there because of that unfortunate human failing, cheating. Without inspectors, you'd be paying a lot more for your fare because you would be subsidising the cheats who would feel invulnerable. As for the industrial action, don't condemn it until you've investigated the root cause of it. Industrial relations in the Underground/railway industries are diabolical. It takes two to tango. The fact that you feel inconvenienced by the absence of trains is tough, but it does not necessarily mean that the strikers are the ones at fault. Down to you to look into it before you rush to judgement, I reckon.
