I think, everything depends on the culture and the way look people in that society at beggars.

Different societies and countries view it differently. In some places, it's treated as illegal activity. Beggers are destitute and are well-networked in today's day and age. If their network's objective is maximum exploitation to get alms, then it's a business. If their networks objective is welfare of their people, then it's a social alleviation - SDG 1 & 2 - No Poverty & Zero Hunger

My Observation, 40 Years ago in India,

• Beggers had no footware; today, most of them have
• Beggers were shirtless, with torn pants. Today, their clothes are dirty but not torn
• Begging bowls used to have dents. Today, they use plastic or stainless steel bowls with no dents.

It could be a business if it's organized and done professionaly.

Depends on the philosophical thinking. It can fall either side.
