Depends on how u look at ba..
For me there two type of monk which i personally classified my own.
There are 'commercial' monks and 'Tudong' wandering monks .
In Thailand the tudong monks wander around in forests,eat,sleep and mediated there...they are cut out from the mainstream society
I saw them in numbers before and i was shocked...the way they live and travel machiam exactly like our infantry soldiers outfield like tat but more worse..The difference is only they wear yellow robes and walk with humility.
They sleep under trees,some build an basha with their holy robes,eat fruits and watever they can find in the forest.

These tudong monks play and learn alot of white magic to defend themselves as one monk told me it is a must as there are many spirits around during the night to come and disturd them..Some spirits even went to provoke them just to test them
These monks hard to find and get info..The founder of Somdei Wat Rakang 1st grand master was one of them..If u can recall he is the one who travel alone and later captured the spirit of nang-nak in the movie nang-nak.
Commercial monks as i call them....They are rich,they are famous,they have aircons..some even have an account with Swiss Bank

These monks are rich and powerful..most of them have very powerful disciples such as polititians,lawyers,judge the chief of state police etc etc u dun wana fu-ck with them..Although a simple media can strip them of monkhood title so they are not that untouchable after all

They are famous for a reason..Thy are good in a particular skill. Some are good in mediation..some are famous for black magic countering..Some are famed for restoring peace and loving kindness in families and relationships..Some good for blessing aquring wealth.
They are so good and famous until that they no need to go out and beg for food anymore...Their loyal disciples will bring it to them and what do u expected ? that the monk shd throw away the food the disciple bring in and go out to beg ?

Some disicple like to curry favour the guru monks so u can very well see those famous monk room very well-equipped one..
Most commerical monks holds great and high ranking titles. So how...with great fame come great advantages .
Leave u to go think..The world has changed
During ancient time..there were only walking by foot
Now there are heavy metals flying aound in the sky at great speed.
During ancient time..the monks can get food easily available..
Now livng in a commercialized world...U try getting food in a yellow robe in hawker centre i confirm u kana fu-cked upside down letf and right lolz

Just an overall thinking of mine...i let the more lau qiao experts to come in and give u a better answer.
