As many others have said...nothing is free as someone (the tax payer) has to pay for it.
However...I think medication for lifelong life threatening conditions which are genetic and you haven't inflicted on yourself such as Cystic Fybrosis (I am AMAZED this isn't free) or lifelong serious asthma should be free. I know if you have a lot of prescriptions you can pre pay etc but my ED and YD are just under the threshold for that. Why is diabetes free and not CF, asthma , even serious depression medication? As they will cost the National Health a lot more to recover if meds aren't taken.
I don't agree with some of the things which people say should be free ..personally I don't agree with free school meals for everyone..unpopular choice perhaps but...if you can pay you should, or provide sandwiches and I am happy to chip in for those who genuinely can't afford it.
I don't agree with totally free uni education..sorry , another unpopular choice perhaps, but it IS a life choice. However I certainly don't agree with the amount it costs now...£3000 or so a year was a lot plus living expenses but £9000?! My kids will NEVER get out of debt...plus a mortgage. Cost wise I think companies ought to contribute...they are the ones who benefit and want employees with degrees so they should pay towards. Two of my kids wouldn't have gone to uni had they been able to do the jobs they wanted to without degrees...they didn't enjoy the work particularly and I have to say some of their essay questions were essays for the sake of essays.
Health wise...Tesco do free eye checks and many other opticians such as Boots do £5-£10 offers at times. So if you want free you can choose. Condoms..again...can get for free. Sanitory products, hell yes, these should be free...bad enough to have the monthlys without having to pay for them too!
Finally, although I am sure there are many other things which I could think of....one thing which does annoy me is people saying they don't have the money for basic items/services but it's not that they don't have it, it's that they don't choose to have the money to pay for it...spending it on expensive phone contracts, SKY tv etc. I speak from experience as I used to go somewhere where I paid (I didn't sign on so had to although money was tight) but many didn't....and they all had better phones, brand new pushchairs (which I couldn't afford), nice clothes and designer trainers etc. Sorry..just had to get that off my chest too!
