The second part, according to some economists, is absolutely fine.

There is no economic law that says the distribution of your expenses over various expenditures must stay equal. If you think about it, there can't be such a law; if it held, since nobody spent anything on electronics/flight tickets/Big Macs/etc. a century ago, you shouldn't spent a cent on them, either.

The richer we are, the less we need to spend on essentials such as food and shelter. That leaves a greater fraction of GDP for things such as healthcare. Most people will say they value health more than possessions, so what's strange about allocating more money to it?

As the existence of such countries suggests, though, I'm skeptical that it's really a technology or innovation problem. We aren't delivering healthcare more cheaply in Europe because we have great healthcare startups or advanced preventative technology, but rather because the sector is structured entirely differently.

If you're like Europe, the population is ageing too - so it's natural that healthcare costs should go up in line with age, rather than inflation.
