...and what they are doing with their time is not practicing to realize spiritual accomplishments, what would mean meditate at least half of the day, cause this actually is what helps you progress with your practice.
No, meditating at least half of the day is not the only means of accomplishment. In fact meditating half the day is not an actual means of accomplishment by itself although if done correctly you will get a positive result.
However practicing 24/7 is the main means to accomplishment. Even so, any practice done will eventually, over many, many lifetimes, get us there just due to karmic imprints. Even just raising one hand in veneration to the Buddha once a day.
I personally find taking the eight Mahayana Vows to be very powerful for myself. Unfortunately I often waste time (or don't have time) later to meditate daily.
However overcoming delusions and developing the perfections, even if not technically on the Path of Perfections, is the real hallmark of progression. An even better real mark of progression is deepening lovingkindness and compassion.
If I am asked to give money for someone's practice who in the end does less practice than me as a householder, than obviously something in this system is running wrong.
You are very proud of your practice time but it shouldn't be a source of denigrating others. We have to support one another actually. I'm sorry that you don't feel support from the monastic community.
