I'm not sure if it's THE problem, but it definitely makes me feel like I need to puke.
It's basically
THE problem. The mindset and perspective of thinking "What's the best I can get" (aka entitlement) instead of "What can I handle, and who would I work best with", is the backbone and foundation of most of these issues. (I'm guessing most marriage issues are also stem from the notion that one "deserves" better, and looking at "What does my spouse have to offer for me" instead of "What can we accomplish together".)
However, this is not a new issue. This has existed for a long time. The richer you were, the prettier a women or more prestigious a son in law you got. We've been grading people forever.
Focusing on things like looks is also an issue, and has also been an issue forever.
The only thing that's a new issue, and the this movement is trying to change, is the attempt to gauge attraction via an image vs meeting live. The argument is the there are many that would connect and generate mutual attraction in person, but do not get to meet because photographs, which are an ineffective arbiter of attraction, have become a standard grading tool prior to meeting. This is the only thing that this "initiative" (it's been an old discussion-there's nothing new the past couple weeks) is attempting to address.
The underlying issues of misplaced priorities and systemic practices which lead to some parties having an easier time in shidduchim than others, is not even on the table.
