Iconditional basic income

Personally speaking I reckon that the inconditional basic income is a bad idea for an economy system. Obviouslly as everything, it have a positives aspects as well such as the help to the homeless, however an inconditonal basic income for those who already work hard, to work harder for the benefitof those lazy people who don´t need to work because is enough with the basic income. Althouhg if you can work in whatever you want, those publics works like cleaner or workman won´t have enough people and the most important jobs  will be full of unqualyfire employees. We live in a society based on you recived what you give to the society, so an inconditional basic income will destroy that society. Moreover a basic income shouldn´t be choose because it drives the economy to a desaster. Unfortunatelly the economical prosperity of the country is before the personal happyness
