Problem is that it might be the case that this culture pass will only be spendable on government-subsidized venues.

In my country there already exists culture pass programs for young/poor people, but you can only use them in big/subsidized concert venues, art galleries, cinemas and museums. You can't use it in more "underground" venues/events which are too small or focused to get government grants, and in my opinion those are very important to culture as well.

Still better than nothing of course.
