What are you even on about?
An FTT is objectively a burden on the banks, not the consumers. Shares et al. (financial products) aren't pure inelastic.
Experiences with 'bankers bonus tax' where it has been implemented (Germany, Scandinavia, Russia) does not remotely show some sort of out-of-the-trend increase in consumer prices for using banking services, even if said bank has both a commercial and a merchant side. Equally, the bank levy in the UK has not led to a notable increase in banking costs for the average person when indexed to any year and most certainly have not even remotely come close to pushing the UK above the European average for year-on-year such increases.
Think outside your year 1 price inelasticity oil/bank graphs for one second... please...
The main non-stupid argument against FTT is the dramatic reduction it causes in investment and share dealing wherever it has been implemented, leading to problems with raising adequate capital and reducing incentives and enterprise.
"The Little Man" is not affected in the short-term by FTT or any other form on taxation, direct or indirect, on financial products.
