People would still pay taxes ;) UBI is essentially a negative tax. If you make nothing - you get some money. If you make some - there's a breaking point somewhere where you pay more taxes than is UBI. If UBI was a cushy amount covering more than the bare basics, low-tier jobs would pay a very small premium over pure UBI.
