Not really sure what your talking about when you refer to "incredible looking baits" as there are so many different baits on the market you couldn't count them all. Many of them work extremely well and many just catch fishermen. I had boxes full of baits but I knew what worked for me on the waters I was going to be fishing on a certain day and time of day or night.
As for muskies being the hardest fish to catch, that's more to do with the the skill of the angler in a lot of cases. In the Kawarthas they're relatively easy to catch when you know where and when to fish for them and getting multiple fish in a day is very common. For many years I kept a log and usually caught between about 80-100 fish per season and my best year was 115 fish in the boat not even counting the ones my fishing partners caught. One morning I went out at 7:30 and by 10:00 I'd boated 9 fish.
Bigger bodies of water like the St. Lawrence or Nippising don't hold as many fish but if you know what your doing and where & when to go you can still do well.
The "fish of 10,000 casts" is only for those that don't understand the fish.
