The plastic bag conspiracy

There is a plastic bag mafia in Finland, I'm sure of it, and sooner or later I'll be able to prove it.
Hell, they're expensive! I mean, not one by one of course. But in the end of the month they sum up to quite a bill... and where do they all end up? Deep inside the trash bin! And then I need to go back to the supermarket to buy some more. I've never bought plastic bags in my life untill now, so I've decided to make the math. 1 plastic bag per day for trash, seven days a week, 20cents per bag give or take. It sums up to over 40 bucks a month... at the end of the year it represents almost 500 bucks. Hell I can do a lot with 500 bucks. I know, I know, I've started to buy cheaper trash bags already, but still... come on! There has to be a better solution. I know they're made out of petrol, and petrol keeps rising. But you guys shouldn't turn it into a trendy thing, to use a plastic bag I mean.
Its surely a governmental conspiracy plot to make the common citizen invest in petrol, even if they don't drive... well it could be.
Everyday I walk the street to realize people walk proudly with their re-used plastic bag, almost as saying 'Yes I've picked it up before leaving the house. I'm ecological, I'm reusing it, doesn't it look nice on me?'
Do you really need an answer, miss and mr Finn? 'Not really!'
Finns are deciding what plastic bag is good enough for trash, and which is useable at the street. Doesn't that seem rather odd to any of you?
If a preety girl carries a plastic bag, she'll always be a girl carrying a plastic bag. She won't look that sexy really. And it becomes even worse when you're shopping in your training suit. Please, what the Hell is that? That's not the trendy Hellsinki I imagined.
Buy a cloth bag and wear a short skirt and a long jacket. It's that simple, and just throw your trash in the bin... who cares really?
