But it isn't actually pricing the native population out of the country, just the most desirable cities. But, that was already happening to a huge swath of the native population beforehand by the native population, so what is different for majority of Portuguese who could never move to Lisbon or Porto? Not much. They couldn't afford to move to lisbon 20 years ago, and they can't move there now.

I see the same dynamic at play here in Boulder. People are claiming there is a housing affordability crisis because outsiders(commonly pejoratively referred to as Californians, Texans, and New Yorkers, even if they're not) are moving in and jacking up the prices, but commonly you'll see those people complaining have been here for, say, 10 years. But, 10 years ago when they moved here, the previous locals were saying...there's a housing affordability crisis and these newcomers are jacking up the prices!
