Problem is things will have to get worse for a lot more people for that to really happen en masse, I support the idea but I wouldn’t probably stop because none of my debts are debilitating. I have a good savings and my only payment is my mortgage and whatever I put on my credit card that month. I’m not going to just stop paying my mortgage for a political movement, and a lot of other people won’t either, supporting or not, people don’t like risking their homes when they don’t technically have to.
All the banks have to do is make examples of a few good people and all the others will likely fall back in line. Finances and debt is something that is very personal to a lot of peopl so people are hesitant to let that flag fly and unite publicly as well.
