Vouchers aim to make agencies responsive by removing the street-level buffer.

Evidence

One approach to change in street-level bureaucracy is to eliminate public workers as buffers between government and citizens. A class of proposals utilizing such an approach is represented by plans to issue service vouchers to citizens. By providing clients with claims on public or private service agencies, sponsors of voucher proposals hope that agencies would be more responsive to client preferences in order to attract their patronage. — Michael Lipsky, Street-Level Bureaucracy, 1396
