Article 14 of the European Convention of Human Rights
The enjoyment of the rights and freedoms set forth in this Convention shall be secured without discrimination on any ground such as sex, race, colour, language, religion, political or other opinion, national or social origin, association with a national minority, property, birth or other status.
If you restrict what people can buy/can not buy based on employment/income status you are discriminating and are infringing freedoms.
So if this was introduced there would be an inevitable legal challenge. This would be a costly business to the tax payer.
Then we have historical precedence for what happens when you restrict access to alcohol. See Prohibition. People simply sort it by illegal methods; so you are talking increased stealing, formation of blackmarkets or bootlegging.
So already determined individuals in disadvantaged groups are put in a position where they are more likely to commit a criminal offense compared to the rest of the population. So thats more cost to the penal system, policing, legal aid and the knock on costs to social services etc.
Oh and bootlegging alcohol is rather dangerous too.
Then we have problems with restricting access to cash. This means people are limited to where they can shop. This has implications for access, particularly for people without cars or mobility issues. Prices become higher through limited competition. This is also more likely to put other small businesses and independent traders who rely on the income from people on benefits out of business as they won't participate in the system or even if they are able to, such a system is liable to be based on non-instant payments to the trader - delayed payments are harder for smaller businesses to cope with.
And what happens to all the second hand trade out there? Its not only more difficult to buy second hand items. It also becomes more difficult to sell second hand.
Its so economically flawed its unreal.
Its nice on paper, until you factor in that humans are not robots.
So, is anyone going to tell me, how exactly, this is going to benefit anyone - out there economically and why this is the solution to the problem rather than other ideas?
Anyone?
