I wouldnt say the game is "rigged", but I would say that:
1.) There are trashy women everywhere. Tinder, Hinge, Bumble, at the grocery store, at the gym.......There are also good ones in each of those places as well. Just not as many as there used to be 5-10 years ago because a lot of women have this false equity outlook on men. I am not going to lose any sleep over not matching with a 7 on Tinder. Its just part of the game. I focus on what I can control and dont focus on things beyond that. The focus is to maximize the potential for each chick that I interact with and make sure that I am doing what I need to do for that to happen (Confidence, strong frame, take the lead and initiate, etc). I also screen very well and I eliminate potential date candidates and not the other way around.
2.) I believe that some men will do great on all platforms, some will do great on some but not others and there are some men who wont do well no matter what they are using to meet women. For me, if I jump on Tinder, Bumble and Hinge, I do fine. I do terribly on POF. I think the more trashy women are on POF and frankly, successful men are intimidating to such low hanging fruit. I probably do best on Bumble and Hinge because the women on there more align to what I am looking for, which is a woman who checks most of the boxes of a potential LTR but I treat them as a plate and see what happens. It seems in my area the women that are financially stable, educated, submissive and have their crap together are on Hinge and Bumble. A decent amount on Tinder. POF is the group of single moms, pump and dumps, etc. So I dont get upset that I am not attracting garbage because its not garbage that I am looking for.
Its all in what you want and where you are looking for it at. Also realizing what you are in terms of your own value and approaching women who align with your value up to 1 up or 1 down and that is the pool that you should be searching in. Whether it be OLD or in real life.
Supply and demand always sets the prices and it also sets the standards and boundaries with OLD. You have your top 10% of men and you have your top 10% of women. They will more than likely be matching through OLD. It is what it is.
I will further your point that, in all aspects of life, the people who complain the most about the way things are typically are the ones that put no effort into bettering themselves and changing their future. Its EASIER to complain than it is to point the finger at yourself and take the necessary steps to become a better person (finances, health, social status, etc).
People are looking for the magic pill or the magic line to use on women and those are the people in that bottom 90% who wont do well regardless of where they are trying to meet women.
As the old saying goes, its lonely at the top. But it's also the best view.
