Most employed people in the UK also have their employer deduct taxes from their paychecks. The difference, though, is that if that happens and if someone doesn't declare their tax affairs as being more complex, the tax authorities assume everything is order and no tax return is required.
I suspect other things have an impact on this system working though, such as the much lower ownership of shares and tax-attracting investments in the UK, as well as the generous tax-free allowance for capital gains (I'd need to make a realized gain of something like $20k in a year to pay any tax on shares, for example.)
