Devils advocate...
Show me the waste, where is this waste you speak of?
Do we get rid of the dustmen (or is it dust people)?
Do we get rid of the nurses?
Do we get rid of the people who are obviously already doing a good job looking after abused children in the London borough of Haringey (tinted with sarcasm here)?
When we’ve culled all of this waste, what do we do with them? Do we ask them to find other jobs, or do they go into our much maligned benefits system?
Do they move to Belize?
I share your resentment, truly – but things aren’t as black and white (or as blue) as we’d all like it to be.
Waste? Look at how healthcare systems are run in other countries. I'm not saying you need to cut the number of nurses though.
Waste? Look at DVLA, what real purpose do they serve other than to employ far too many people to administer a database (much of the taxing, etc is done online now anyway).
Waste? Look at the MOD spending on projects that never come to fruition.
Waste? Look at NHS IT system.
Waste? Look at government quangos.
So for a country to be able to develop further - taxes should be reduced?
Lower taxes benefit the economy, and the government still gets a large chunk of the money anyway in the end.
If you have lower taxes, the people have more disposable income - they are able to buy more things, better things and also spread money over more companies.
So instead of being able to spend only £50 with company A, they can now spend £50 with A and a further £50 with B. (government still gets a nice cut via VAT)
This means that B is now doing more business, so is making larger profits and paying more tax ... but wait, since they are doing more business they are likely to need more people - so now they have just reduced unemployment as well.
Lower taxes help the whole economy grow healthily, this is why the best form of government for a healthy economy is a small one - where the government only regulates and carries out the critical functions - keeping taxes as low as possible to allow people to spread money throughout the economy - benefiting more companies.
