> I meant foreign workers

So did I. Being foreign, they can work at home and not pay into a system they have no part of. Problem solved.

When you move to live and work in Vienna you become part of the system since you pay income + other taxes, just like the locals, except unlike the locals, you don't get social housing.

Unless of course ... your comment was just an anti immigration dogwhsitle from the start, in which case you should just said THAT instead, and not waste people's time with cumbersome allegories masquerading as arguments.
