People have the responsibility to decide what to do with their lives.
The people who write these articles are espousing their own opinions, and, as is many times noted in the little blurb at the bottom, these views are not necessarily shared by the publication.
The advertisers, as long as the services they advertise are in accordance to HALACHA and not some random person’s idea of what is proper, do nothing wrong by supplying and advertising these services. The same goes to the magazines.
Many people who go to hotels go for other reasons than to act as spoiled rich brats while poor people are starving, believe it or not. Those who go to the luxury places are usually quite generous with tzedakah, and those who are not or are not enough will find out the truth after 120. Their life choices are their own and their consequences are their own.
