Lisbon a collapsing museum 2

I really don't understand why these beautifull buildings don't get saved. Okay, Economy is God in these times but still. it does not look very smart to me for the future. In Amsterdam we have institutions and rules to keep the old hart of the city as beautifull as it is and there is economy God as well, but they think more about money in the future as well, because without the ancient buildings there will come not as many tourists! And there is a squat law. When buildings are empty longer than a year you can squat them. That means less homeless people. But here they don't seem to care about the buildings and the homeless people. I see both a lot on the streets.
