Why do Professionals have to go through 'Many years of Studies' to be Licensed and Politicians don't?

Why do 'Professionals' have to go through 'Many years of Study' to be Licensed and 'Politicians Don't'? 'Political Offices' are very important and it takes a 'dedicated Individual' to fill the Offices. Its not just a 'Job', its a 'Life-Style'. Politicians should be the 'Real Individuals' that 'Genuinely appreciate' their 'own Freedom and Equality' and hence, that of 'every Real Individual' at the 'Bottom' of the 'Political Entity'. Living and 'Occupying Political Office' in a 'Democracy' is no small Thing. It takes a 'Wide Perspective' and a 'Tremendous amount of knowledge', both Local and International to 'Fill' 'Political Office'. Of course, on the 'Moral Side' one can also add, 'some degree' of 'Humility'. There's no Room for 'Egotism' at that 'Level' of 'Functioning and Importance'. In a 'Democracy', the 'Most Important aspect' of 'Governing' is the 'Freedom and Equality' of the 'Real Individuals' at the 'Bottom of the Entity'. Leaders of 'Poor Moral Stature' and 'Limited Intellectual Capacity' to 'Govern' do not belong at that 'Level of Functioning'. At that 'Level' its no longer about 'Ego, its about 'Service' and 'that Service' is to the 'Bottom' of the 'Political Entity'. 'Political Office' is a 'Great achievement', and it should be 'Limited' to 'Morally and Intellectually' 'Qualified Real Individuals'.
