Difference is, now this has been put into commercial hands who a) sniffed a bargain in the first place and b) know how to run it as a profitable ents venue, said Dome is on to quite a good little earner, iirc now the most popular indoor venue in the world.
1.) Taxpayer not received anything in return and the €1 billion was cost of building it, cost of running it until given away was another €200 million.
2.) Profitable ents value for performer ....Yup, for the stager of the events .....Yup for the company with the lease..............Not taxable profits so taxman gets zilch
Overall payback is longer than either of will be alive and thats assumming both of us reach a century plus.
Spain hasn't the only follys as UK has even bigger ones at taxpayers expense.
