If the subway costs $1 and 50% of the jump the turn-style 50% of the time the cost to ride the subway in aggregate is $0.75
Sure, if you take some asinine ideological hard line about the goodness or badness of taxation you'll probably get your panties in a knot but if you look at it from the perspective of who's spending money in the economy a little bit of broadly applied fraud and a little bit of tax reduction are the same thing because they shuffle money around in the same manner.
No, you have jumpers whose aggregate cost is $0.50 and non-jumpers whose aggregate cost is $1.00. The revenues realized are $0.75 a ride, but the costs aren't distributed evenly. If the jumpers were caught, then the cost could decline to $0.75, the nonjumpers would pay less and the jumpers would pay more. That world is better for the half of the population that doesn't jump.
Sometimes called “principled”
back then you could file your taxes with 6 or 7 kids and no one would check
that is not the same as claiming you have 6 or 7 kids that will be filed on your taxes and then just never filing it. Once filed he would need SSN for those kids, or he would owe taxes
