I think I’m surprised this doesn’t happen more often. Maybe I underestimate how good the police are at prevention of this crime.
Doing a kidnapping and getting a ransom is probably not too hard, but being on the run forever afterwards might not be worth it to most. People with money can hire their own bounty hunters/or plain criminals to go after them afterwards. Or just announce a bounty high enough (in dark channels, your high profile security company has access to) so people will do the hunt for free.
Most people like to boast about their action - so competent here means keeping quiet about it forever and coming up with a good excuse for why they have that money.
