I tend to agree. Selling is such an iffy thing. You invest a huge amount of time and personal energy on something that may fall through at any moment. However, if there is monopolization, it should be stopped. I am a very long time user of the 'Net (since before it was the 'Net), but there are some things you can't buy over the internet; you just have to see them in person.
Having been in the business for many years....sometimes an agent is overpaid and sometimes underpaid...but most offices have a situation where 20 percent of the agents make 80 percent of the commissions. It's just the nature of the critter because most companies use the shotgun approach to having agents....have as many as you can because each has the potential to bring in business even when they really don't work full time.. I doubt if there is any where in the country where a home seller can't negotiate a commission...but just as almost everything in our country...you get what you pay for..your choice.
