Using cable service was a bad example on my part. I was trying to make a point about how market drives pricing, but cable, like health care is a service not a product and they do not face global competition like the manufacturing industry.
From a consumer standpoint global competition is a good thing. I am all for it. The point I was making is that the system is unbalanced or unfair at times. What I have learned over the years in industry is that if you or the company performs poorly, then eventually you and/or the company goes under; but the converse is not always true. If you perform well and the company performs well; you may still loose your job. Success is no guarantee.
Here is how global competition has been good to us as consumers. The government's CPI has some funky calculations so I reference things to the price of a gallon of gasoline. (Price based on my region over the years.) I will use a television set since they have been in production for several decades. I recall that my dad bought our first 25" color TV in late 1968 for $400. That was a SOTA TV and a lot of money. $400 back then bought about 1800 gallons of gasoline. Today, consider a 60" 3D HDTV as SOTA. It costs the equivalent of about 788 gallons of gasoline. Quite the reduction in cost over the years thanks to technology, productivity improvements and competition. How about USA made high end gear? I will use my favorite preamps for an example. The ARC SP-15 top of the line preamp cost the equivalent of about 4500 gallons of gasoline in the early nineties. Today, their top end Ref 5 costs about 3800 gallons of gasoline. So maybe global competition has been good for the hifi market as well. Maybe, if I compared the 40th Anniversary edition to the SP-15 it would not look so favorable, but I'm not sure that is apples to apples.
Now, look at the service industry which apparently has no global competition. I can recall my cable bill was $20/month in 1989. That is because at that time the bill increased 10% per year and I made up my mind that when it hit $20/month I would cancel. (I would dance in streets today for a bill like that.) So that was equivalent to about 16 gallons of gasoline per month. I still have basic cable and if I back out the internet service and just look at cable, it costs me 27 gallons of gasoline today. That is an 11 gallons of gasoline per month increase! For the same basic service! How about healthcare? I was paying $22/month for healthcare in 1990 when my oldest son was born. btw- It was an HMO and his birth cost me $10 out of pocket. I miss those days. So in 1990, my healthcare insurance cost was about 18 gallons of gasoline per month. Sure, I have changed companies over the years, but I have been with the same company now for quite a while and have still seen big year over year increases. So much so that today my healthcare insurance costs me a whopping 100 gallons of gasoline per month! That is a 455% increase in gallons of gasoline over 22 years! Yikes!
