I've been watching some documentaries on the 60s, and I'm a little confused about the day-to-day functioning of hippie movement, especially during the Summer of Love.

It seems like few, if any, in the movement were working or making money. There were "free shops", offering goods for no cost, and there were a lot of communal activities like free meals. But who was supplying these basic goods if no one was actually making any money? Where was the money coming from?

Was the movement supported by outside money (e.g., trust funds, parental allowances, savings)? Did the hippies go into debt to support their lifestyle?

Some of their events must have cost a significant amount of money to host, but contributions from the community had to have been minimal - money has to be coming from somewhere! Were they supported by "hippie tourism"?

Thanks guys!
