Jugendherbergen (Youth Hostels) are everywhere in Germany, making travel affordable even in expensive cities especially if you’re under 28 and/or don’t mind sharing a room.
The same might apply in other countries, I wouldn’t know. Except in France where I know it’s not the case because they are sadly underfunded.
Industry is irrelevant for tourism. No, Germany absolutely has beautiful towns and landscapes, although it’s not like the countries you mentioned where almost every place in a popular region meets that definition. That’s where travel blogs and guides come in handy to find the places worth visiting.
