Tried your website on Chrome 108.0.5359.125 (Win 64-bit), and it displayed nothing but a teal background, until I turned off the Decentraleyes 2.0.17 extension (which was reporting and blocking 542 locally-injected resources). FYI.
Monaco is incredibly safe - undercover and uniformed police everywhere, ubiquitous video surveillance, few ingress/egress points, thorough filtering of cars coming in and out based on condition and license plate, etc. It’s a small territory and thus easy to monitor.
Most Monegasques are by and large not millionaires, but they are indeed taken care of by the welfare state very very well. However, they barely make up 25% of the residents, so they are overshadowed by the wealthier foreigners who set up residence in Monaco.
Re: the mobile workforce, there's a tax treaty between Monaco and France (which was imposed by the latter after a total blockade of the former in the 1960s) by which French citizens working in Monaco still have to pay income tax in France, even if they are Monaco residents. It's the only case of "global taxation" of French expatriates in the world. There are, therefore, no incentives for them to live in Monaco. People who set up fiscal residence in Monaco to avoid taxes are, therefore, not French.
