Less and less industries today have any remaining barriers of entry. Some still remain, though. Race and gender issues being the most obvious (I find it shameful and outrageous that this is still a problem in 2016, but evidently it is). Another fantastically blatant example is having a non-US non-European citizenship and being unable to relocate to San Francisco Bay Area, wherever this magic wonderland filled with ponies and unicorns is. Others, like access to education, are disappearing very fast, despite all resistance of the education mafia. Thank you, Wikipedia, I owe you so much.
