"We have to take into consideration that for some , mainly the ladies because of the lack of male dancers,, if they want to dance a little more seriously there is no other option but to dance Pro/Am."
That's what I was alluding to when I wrote:
"some of it is the best option available to the student under the circumstances - especially those who may have taken up ballroom later in life."
However, it can't be ignored that this effective expectation that ladies in a certain age bracket will do pro/am if they want to dance doesn't exactly help with the development amateur men in that age bracket. There probably wouldn't be enough of them to go around anyway, but the assumption tends to limit the interest.
"To some money is no object. I could site this case of this lady who pays all the bills. She and her Professional partner flew like some 10.000 miles each way to the USA and back to compete in a comp held in Ohio."
People paying premium prices at top competitions presumably are somewhat aware of the range of options, and so if they choose the most costly form of pro/am that's their right. The concern/criticism is more when forms of pro/am that are outrageously overpriced for their value are pushed on students who are too new or too isolated in a small town to know that they are getting taken for a ride (financially speaking).
An issue that came up earlier in the debate is that the parts of the dance industry that practice this may be not only uninterested, but actually incapable of effectively training an amateur couple - if a middle aged husband and wife walk in the door, they get steered into separate pro/am not only because it's more lucrative, but because the knowledge to develop them together and help them navigate the challenges they would face is actually lacking.
