If increasingly more spending is ok, do you support 34T debt or unlimited debt?
Should taxes have an upper limit? 50%? 70%? 90%?
Should you not be upset even more that no matter how much tax is collected, govt has insatiable desire to keep spending more and more? i agree "Rich need to pay their fair share", but what is "fair share" govt should be collecting?
We just finished building https://clubsall.com, we implemented this, we call them clubs.
e.g. when you subscribe to "technology" club, you get content from multiple "technology" communities. You can also post a message and tag multiple clubs.
The main difference seems to be that we have pre-defined clubs that aggregate communities.
In your case, seems like every user can create their own groups. Honestly, intriguing idea.
