In 2014, he was awarded the Prize for Liberty by Nova Civitas.
De Keyzer is, among other things, a strong proponent of the principle of a basic universal income. In a recent article in leading Dutch-language business newspaper De Tijd he argued, "A guaranteed basic income provides a solution for people with few job skills. Nowadays a lot of relatively uneducated people have too little to offer in order to warrant even the gross minimum wage. Today someone who is able to deliver only 700 euros of added value per month will not find an official job because an employer would be obliged to pay him or her not less than the gross national minimum wage of 1500 euros. This means that people with low educational qualifications remain unemployed, living on a social security allowance of 1100 euros. Setting a guaranteed basic income of 800 euros would solve the problem for both employers and the unemployed. The undereducated can get a job and will have much more left over for themselves at the end of the month than someone who is not working at all. Meanwhile the employer can afford to hire such people at a wage level that makes them worth their pay."
At the same time, De Keyzer argues for a free market economy in which prosperity and growth are driven not by state intervention but by a process of ‘creative destruction’. He recently wrote on this subject, "Are we poorer today because people no longer plough the fields manually or weave carpets by hand? Or because dairy farmers do not bring bottles of milk round to our houses anymore? New technologies foster greater prosperity and boost purchasing power. And we will be spending this money and these resources on services, products and experiences that we cannot imagine today. Of course this does not make life any easier for people whose jobs are at stake today. However, you are not going to help those people by entertaining misplaced nostalgia about how everything used to be better before and making attempts to hang on to doomed jobs. What will help, though, is thinking seriously about how they can contribute to prosperity going forward."
De Keyzer completed his secondary education at the Our Lady of Lourdes College in Edegem, obtaining his high school diploma (sciences option) in 1993. He then pursued higher education studies at the University of Antwerp, where he was awarded a Master’s degree in economics in 1998, graduating magna cum laude.
