AS was said in an earlier post, the criminal element are probably the ones who could most easily afford to pay any increases in visa fees!
Without wanting to sound like I'm just blowing my own trumpet, or go off topic, I am in a position where I have been retired in Thailand for quite a few years, (and consequently spent a few million baht here) and have seen the Exchange Rate drop from 73 baht to the British Pound to about 40 baht. Also, being honest, I notified my Government that I was retired here and they very kindly froze my Old Age Pension so I no longer get annual increments. Add to that, the increase we have all seen in the cost of living, and I am the kind of person that Big Joke would want to penalise by increasing the amount of money I have to put on deposit in a Thai bank, rather than the criminal element that he is supposed to be trying to eliminate?
