This is not an accident, and the fact the compliance cost far outweigh any tax benefit yet the burden remains make this crystal clear.
Edit: to all the people offended by this comment. Ponder why international banking is infeasible for the domestically banked and then question why that may be and whether the state of things may be for the benefit of governments to better control their populace. Thus you will understand this comment wasn't actually about impugning the common domestic bank account holder but to show some incentives that keep them locked in domestically. If you pointed out why international banking is infeasible then you finally got the point of my comment and perhaps some understanding of why some third world people may be desperate enough to use an evil pyramid scheme environmental wrecking shitcoins like bitcoin or ethereum etc.
