Dumbass question 
What if in future, for example in year 2100, the bitcoin will be used by everyone.Working for bitcoins shopping for bitcoins,paying bills,etc.. So if an worker will work for 0.00100000 Satoshi/month, his employer will pay 0.00020000 Satoshi blockchain tax. This is 20% tranzaction fee. Is an huge tax and will ruin economy.And people with big tranzactions means very rich people will pay an infirm amount.. Can this be changed in bitcoin protocol if is needed?
