They do realize that the stock market is closed on Saturday right? Why not have their day of rage when the market is open, unless they know it is going to be a bust and don’t want the briefcase brigade to laugh and throw coffee cups at them.
Perhaps to them, every day is a weekend when they are living on the dole.
They want two days for their antics during which the police can ignore them. I think they will be gone by Monday.
If they start doing something on a weekday, in any sane society they'd be washed off the street, or tear-gassed, or shot with plastic bullets - and whoever remains alive would be jailed.
