>>1601People don't really value abstract ideas on a general basis, for example everyone can agree a good electrician can get things done and fixed but a good painter will get opposition as some might say a photographer is more effective and cheap, some others might say a sketch artist/draftsman is also cheaper and quicker, so on and so on.
Same happens with musicians, some say a jukebox or a stereo is enough, an artist will always get people doubting them due to their value not being seen by everyone. An artist has to pander to a certain sub-group to have constant work and the more niche/specialized the harder it is, hence why the most successful artists are either friends of a very rich eccentric, a stylistic whore with no integrity and/or a money launderer. Successful doesn't always mean best, in fact it usually is the opposite but some exceptions exists and they should not be seen as rule of thumb, they are oddities, most accomplished artists died without knowing they were/would be cherished.
